A quick search on Wiki comes up with the following.
Laws vary from state to state in the United States of America, however 30 states statutorily ban weapons at post-secondary schools. Of the 20 states where licensed concealed carry is not legally forbidden, 19 allow schools to adopt their own gun policies. It is exceedingly rare for schools in these 19 states to allow licensed concealed carry by rule. The two best-known examples are Colorado State University, and Blue Ridge Community College, in Weyers Cave, Virginia. Utah is the only state that specifically requires public universities to allow licensed concealed carry on their grounds.[3] Further, a 2003 study revealed that 150 major colleges and universities restricted firearms in some form. A total of 82 banned guns completely, 25 required them to be stored in a central facility, and another 27 restricted possession to certain groups such as ROTC units and shooting teams.[10]
Concealed carry is legal in most areas of the United States. A handful of states and jurisdictions restrict or ban CCW, but all states except Illinois make provision for legal concealed carry via a permit or license, or via constitutional carry. Most states have "shall-issue" statutes; that is, if a person meets the requirements to obtain a permit, the state must issue one. Some states, including California, New Jersey, New York, and Massachusetts have "may-issue" statutes; these states may (or may not) issue permits to carry if a person meets the requirements to obtain one. States with may-issue statutes typically do not issue permits unless the applicant provides a documented need for a concealed weapon, such as for retired police officers, judges, and federal agents.

Texas legislation.
Restrictions on licensed concealed carry
While a permitted resident of Texas (or a nonresident holding a recognized permit) is generally authorized to carry concealed in most public places, there are State and Federal laws that still restrict a permit holder from carrying a concealed weapon in certain situations. These include:
Federal buildings - Premises owned by the U.S. Federal Government or its agencies for the purpose of any official business of the Federal Government are covered by Federal statutes that supersede State law. It is illegal in general under said statutes to possess a firearm while in any such location, and possession of a State-issued concealed firearms permit is no defense. Such places commonly encountered include post offices, Federal courts, and offices of the IRS, FBI, Justice Department, Department of Energy, USDA, FDA, etc. A rider tied to the 2009 Federal CARD Act has restricted the Department of the Interior from enacting or enforcing restrictions on carry of arms within federal parks and preserves; CHL permittees may carry concealed while in a federal park or wildlife preserve contained wholly or partially within the borders of the State of Texas. However, Army Corps of Engineers properties (including all reservoir lakes and included park areas) are still off-limits.
Schools - It is a felony under TPC section 46.03 to carry a concealed weapon (licensed or not) inside a building of any educational institution, or any building being used by an educational institution for educational purposes (such as temporary, overflow or emergency facilities). The age/grade level, funding type or for-profit status of the school does not matter. Carry of a concealed weapon while in a public outdoor area surrounding an educational building is permitted; as defined by TPC 46.035(f)(3), "premises" refers only to a building or part of a building, and does not refer to driveways, streets, sidewalks, parking lots, or parking garages.
Public sporting events - It is a Class A misdemeanor to carry while inside a building currently being used for an interscholastic or professional sporting event, unless the person carrying is a participant in the sporting event and said sporting event requires the use of the firearm (i.e. a target shooting competition).
Businesses posting a compliant "51% sign" - It is a felony to carry a concealed weapon while on the premises of a business that makes more than 51% of its revenue from the sale of alcoholic beverages for on-premises consumption (colloquially "bars", "nightclubs", "taverns", "saloons", etc). A person with a CHL that is in violation has a defense that the establishment did not post the proper signage, as required by the Government Code section 411.204. The proper signage contains similar language as is required of all liquor license holders, but with the addition of a couple of words to prohibit licensed as well as unlicensed carry, and a background containing a red "51%" to make it obvious at a glance that the sign applies to CHL holders.
Correctional facilities - It is a felony, whether licensed or not, to carry inside a building generally termed a "jail" or "prison".
Courts or court offices - It is a felony, whether licensed or not, to carry inside a building used by a functioning municipal, state or federal court for official business.
Election polling places - It is a felony, whether licensed or not, to carry inside a building being used as a polling center for any municipal, state and/or federal elections process on the scheduled voting date or while polling is underway. This is significant, as a local business which would normally not prohibit concealed carry may offer their facilities for use as a polling place. A person would be in violation if they entered the building on the day voting occurs, even if the polls are not open at the time, and even if the license holder is there for some other purpose than to vote.
Racetracks - It is a felony, whether licensed or not, to carry a firearm on the premises of a racetrack (horse, dog or automobile).
While intoxicated - CHL holders may not carry in any place or at any time while they meet the legal definition of intoxicated, including having a BAL of .08% or greater, but also including being under the influence of any one of a number of intoxicating substances including certain medications.
I can't find anything that prohibits those licensed to carry concealed weapons from taking them into movie theatres (unless they are licensed for alcohol). I'd be interest to hear Beaglebuddy's take on this?
Nuclear bomb....such a proud achievement...
They defiantly think that they are the center of the Universe
We invented wine casks,utes and the cork hat...no flies on us
One thing is certain, Americans of all political perspectives are not looking for sympathy from any people in any other country.
Im sympathetic to the victims, not the law makers.
We have a problem but we will deal with it ourselves without any outside interference.
Like sweeping it under the carpet until it happens again.
And actually we are the brightest bunch on the planet, who invented the nuclear bomb, put a man on the moon, invented the computer, internet, windsurfer on and on.
Inventing things is great but using them correctly is another 
Being a movie theatre it wouldnt have the 51% sales of alcohol so I dont think the Federal (or is it state?) prohibition would apply. This particular shooting happened in Colorado where different State laws would apply.
Many companies reserve the right to prohibit weapons on thier property- might have been the case here- or just a simple case of nobody in the audience happened to be carrying a weapon- or was able to fight back.
Its a bit hard to see when your eyes are full of tear gas or smoke.
Maybe tear gas and smoke grenades should be banned...........
^^^ but worth mentioning that open visible carrying of a firearm requires no permit. You can have a pistol or revolver in a holster outside your clothing in many many states / counties. CCW permits only relate to ability to have concealed firearms on your person. Overseas people often don't realise that
Guns & the good ol' US of A. Jesus wept…..
The American constitution was written in the 1780's & came into effect in 1789 – about 223 years ago. Written at a time when the US was at war, without a formal military as such. That wonderful (insert sarcasm symbol here) amendment allowing the 'right to bear arms' & a regulated militia etc was appropriate at that time. I question its appropriateness now.
If shootin' is your thing so be it. At one level, I can appreciate the technical aspects of shootin' & huntin', it's certainly not something I'm interested in. Yes, I've fired a couple of handguns & gone hunting rabbits & roos, but not an everyday thing for a city boy like me. The idea of spending an afternoon at Swanbourne rifle range (or where ever) is about as exciting as watching grass grow IMO.
I can appreciate (but not necessary agree it's 'necessary') that many US citizens might own a hand gun arguing 'personal protection'. I can understand the huntin' brigade owning a rifle or two, a shotgun or two for duck huntin' & for farmers to own guns as working tools.
Short of being in a war zone, what the **** does anyone do with semi-automatic weapons? What's the “need” to own a MAC 10, or a Street sweeper, or an AK47 – or insert semi-automatic weapon of choice? Owning a .50 Cal sniper rifle is a “right”? We've all heard the line “with rights come responsibilities” – but seriously, America it's time to grow up.
The yanks fought for their liberty 220 odd years ago. They won. So get over it. It's time for America to build a bridge & move on from that. America's ongoing reliance on this argument about 'liberty being at risk if I give up my gun(s)' is a sign of their national immaturity IMO.
Until they are prepared to address the issues about access to & ownership of guns, the US will continue to have incidents like Colombine, like the movie cinema…and they will have no one to blame but themselves.
So many guns, it's a matter of time before some suicidal dude kills his twin brother by mistake..

Juddy, I can tell you what people do with semi auto firearms.
Cull vermin more effectively, that's what. Rapid follow-up shots are sometimes needed for humane culling and also when multiple running targets are encountered in thick bush. Feral pigs and rabbits doing the bolt are good Aussie examples.
Mark,
sure, that would be reasonable IMO....explain to me please what use an AK47 (or similar semi-automatic weapon) is for pig huntin', pickin' off a few rabbits, sorting out feral animals etc? I've got no prob with their use for farmers etc....but some city/suburban guy or girl owning an AK/SKS/AR15 'cause s/he likes to shoot???
Nope - owning weapons designed to kill humans (not animals) simply doesn't fly.
