A man shot and killed at least 14 children and one teacher at a Texas elementary school on Tuesday, the 27th school shooting in the US so far this year.

The man who was killed by the police was identified as an 18-year-old from the local community, who is some 80 miles west of San Antonio. The man entered the school with a handgun and a rifle, although details of the weapons and how he got them are still to be confirmed.

What happened in Uvalde is a horrible tragedy that cannot be forgiven in the state of Texas. The National Refile Association's annual meeting this coming weekend in Houston will feature a speech by Abbott, an enthusiastic promoter of gun ownership.

Unlicensed carry, lower minimum age, no federal limits

Under the Unlicensed Carry Law, anyone over the age of 21 can carry a handgun in most places without any training or permit. Texans still need licenses to carry guns in schools and colleges, although requirements can vary depending on the school and location, and private businesses can also ban guns.

In Texas, the minimum age to own and carry a gun is 21, but a new law that took effect in September allows people under the age of 21 to buy a handgun if they otherwise meet the requirements to own one. According to the new rule, people who are under threat of family violence, including stalking, can submit a request for a gun license.

Other gun-friendly laws allow foster homes to store guns and ammunitions together, rather than separately, and junior marshals can carry concealed guns instead of storing them in schools and colleges.

The Second Amendment Sanctuary Act was signed by Abbott during the legislative session. Government agencies in the state are not allowed to sign contracts with businesses that discriminate against the firearm industry.

A survey done by the University of Texas and the Texas Tribune last April found that almost half of Texans were in favor of making gun laws more strict.
