PD and certain cars

I’ve noticed certain cars used for robberies have more aggressive responses from the police. Now if you are a criminal you are to follow the unwritten 5 minute rule no swaps, no jumps, no blocks. But it’s cool for PD to pit you into spikes before the 5 minute timer is up. It’s a huge double standard. I understand “crims cant always win” but if I have to follow and unwritten rule so should PD <3
