They attempted to murder someone in a car accident. If 10 cars were involved, she was probably pushed into their car by someone behind her. So the cops arrested the suspected federal agent for attempted murder, right? NOPE! Cops are not on your side. Ever.
Without their cars, they are 100% useless. That's why they freaked out and started shooting when they thought that they were immobilized.
Spike strips stop cars. Nobody on the south side can slash a tire? WTF?!?
