create better security in all schools across nation, like a panic button, bullet proof doors, armed plain clothes guard

i am a mother of a 5 year old child. my life along with everyones life has changed on dec 14th when a man with a gun shot through doors to elementary school and massacred many children and teachers. i have thought school to be relatively safe until now and i think this tragedy calls for immediate attention to protect our children better. i am asking for bullet proof doors, panic button ,and armed guard in plain clothes. they have armed guards in malls surely our children are as valuable as anything in a mall. the children count on us adults to protect them and we need to do our job better and keep them as safe as we possibly can
