Parents fight for increased security at Highland Park High School

HIGHLAND PARK, Ill. (CBS) -- Some parents in Highland Park are calling for tighter security after a student brought a gun to school last month.

"How can they think for one minute, after April 4th, that our schools are properly secure?" said Suzi Wahl of Parents Secure Our Schools.

During a rally at Township High School District 113 headquarters, parents demanded metal detectors and additional armed guards.

They said they have spoken out at two separate school board meetings since the April 4 incident, which forced students into a hard lockdown.
