SCHOOL -[FLORIDA]- SECURITY

THE Florida high school where a gunman killed 17 people in February opened on Wednesday for a  new school year with three armed guards and other new security measures that-

Some parents and students  worried  would not be enough.

Marjory Stoneman Douglas High School in Parkland, Florida, doubled its campus security detail to 18, including three armed uniformed sheriff's deputies.

The school's 3,300 students wore new identification badges as they funnelled through three entrances at the sprawling 45-acre campus.

During the school year, only one heavily monitored entrance will allow visitors on campus.

''I know the extra security is necessary, but it makes you know that your school isn't normal,'' Nariah Depina, a  15-year old sophomore, said as, she arrived for the first day of class.

School administrators considered and then against requiring students to use see through backpacks or installing metal detectors, finding if would be too difficult to screen all students each morning class.

On Feb. 14, in the third deadliest shooting by a single gunman at a US school, police say Mikolas Cruz, 19, opened fore on teenagers and teachers with an  assault-style weapon.

Cruz, who had been expelled from Stoneman Douglas, is awaiting trial on 17 counts  of  first-degree murder.

The latest outburst of violence in a decades-long series of  shootings at US schools and colleges prompted   Stoneman Douglas  students to help form a nationwide  youth-led  gun control movement.

The US  House of Representatives  did not tighten gun laws but did approve more spending for school security.

Broward County schools Superintendent Robert Runcle defended the security decisions, including the lack of metal detector, from criticism, by parents and some school board members,but acknowledged that anxieties remained high.

In addition to more security personnel, including the number of armed law enforcement officers    increased to three from one, students were greeted with classroom doors that lock automatically. [Agencies]
