Yes, if someone is speeding on the streets and a police officer sees that - that's fine, let them go, we'll send them the bill later.
Of course, they might catch a few mothers with prams on their way to said home, but that's a reasonable price to pay for not wasting so much time pulling people over!
Police having poor training, being too trigger happy and having very little repercussions for having done terrible things is a completely different topic.
Are you under the impression that people pulled over for speeding are immediately removed from their cars and taken to jail? As opposed to, say, being stopped for 15 minutes, given a ticket, then allowed to go on their way. How’s that end up any differently for those poor mothers and their prams in your little GTA fantasy?
