“There’s more hate for the police officers than there is for the shooter.“
No they do not. Americans are just done with do-nothing, worthless government employees and politicians.
That is worth repeating. The hate isn't directed at police officers in general, it is directed at the cowards who failed to act to try to save kids in the school. While unarmed teachers and students were taking actions that got them killed in order to save students two armed police officers were hiding outside.
The biggest lesson from the Parkland massacre was that the idea that the government and trained police with guns will protect you is totally false.
