Another school banned backpacks to prevent hidden weapons from slipping through, while others changed dress codes to forbid heavy clothing such as the trench coat Pagourtzis was said to be wearing to hide his weapons.
Gillard said the gunman kept shooting despite a fire alarm to alert authorities. It's unclear whether the suspect's father was aware that his son had taken the weapons.
"If we're dealing with student stress and anxieties and any bullying situations, then the problem will never come to the point where a teacher would even have to consider using a gun", she said. Abbott said he'll meet Wednesday with gun rights and gun control advocacy groups and Thursday with victims of the attack at Santa Fe High School and the November attack on a church in Sutherland Springs.
One gun-control group, Texas Gun Sense, said it will push this week for tougher background checks on gun purchases, suicide-prevention programs, gun safety at home and so-called "red flag" laws that restrict gun access for people identified as potentially unsafe. So will Texas Gun Sense, which promotes common-sense reforms to prevent violence.
Senior Pastor Brad Drake said before Sunday's worship that the church's objective is to "offer hope and healing that we understand only comes through a relationship with Jesus Christ".

The whole ordeal lasted about 25 minutes, said Trochesset, adding that he did not believe any children were caught in the police crossfire - though autopsy results are needed to confirm that.

After the 2012 assault on Sandy Hook Elementary School in Connecticut, Texas allowed teachers or school employees to carry handguns on campus if they met certain training requirements.
Almost 200 Texas school districts allow staff to carry guns.
Abbott said he would talk with educators, parents and elected officials about ways to improve school security without infringing on the right to bear arms, protected by the Second Amendment of the U.S. Constitution.
Starting today, there will be an armed police officer on each campus in the Mansfield ISD, which has 44 schools and more than 34,000 students.
Sadie Rodriguez, the mother of Shana Fisher, 16, who was killed in the attack, told the Los Angeles Times that her daughter rejected four months of aggressive advances from Dimitrios Pagourtzis, 17, who is in jail accused of murdering 10 people early on Friday at the high school in Santa Fe. Fourteen students and three staff members were killed, while 17 others were wounded.
A handful of lawmakers have called on Abbott to convene a special legislative session to address school safety.
