So let's add this to all the other failures by the EffingBI, the school,

and the Sheriff's Office:

BREAKING: Deputy and counselors recommended institutionalizing Nikolas Cruz long before deadly massacre at Florida school.

— The Associated Press (@AP) March 18, 2018

School counselors and a deputy wanted him institutionalized under Florida’s Baker Act, which would have made him a prohibited person, but that never happened either.
But let's blame the gun.  And the NRA.  And the Stupid Party.  Blame ANYONE except the murderer and the idiots who had dozens of chances to do something, and failed.
