Heres the back story......
Broward county Liberal Politicians didnt want the Stats to show that they were arresting minority Juveniles and as such they had in place a new program where they cowered the Police and Sheriffs into lowering the arrested minority juvenile number by ......wait for it...... NOT arresting minority juveniles....Brilliant, eh???..
SO they went to the kids house 39 times and had to walk away to adhere to Liberal policy.... the kid has a Hispanic last name and as such they couldnt do anything to him lest it reflect badly on Hispanics.
So Liberal policies castrated willing Police to tow the deadly Dem Policy and have gotten more kids killed.
Does not explain why they did not enter the building while the shooting was going on.
