Tuesday's shooting at an elementary school near Atlanta, Ga., has some parents locally wondering about school safety for their own children.
In Prince George's County, students will return to class in the midst of $7.5 million in security upgrades.
Student Michael Cosby notices some of the more obvious changes as he headed to Oxon Hill High School Tuesday morning.
"I noticed clothed police officers in suits. I noticed they had badges and guns," Cosby said.
In addition to the police officers, the $7.5 million will also be spent on a improved CCTV system, entry systems that require cards and panic buttons.
"If a situation were to occur where you could not get to a phone and call 911, you could hit a button very quickly that would alert our dispatch office who would in turn notify the police," said Rex Barrett, Prince George's County's assistant director of school security .
