This is exactly why you NEVER EVER call the police. Defund these motherfuckers.
Defund the police not the answer. Demilitarise them instead. Training.
There is a failure across the board to enforce the law. Murder no doubt so prosecute. Enforce the laws already in place. Especially politicians and those on the public payroll.
This case is a severe lack of training. If they saw boiling water as a potential weapon then don't tell the potential threat to pick it up, not rocket science. There was no reason for them to draw their weapons.
