I have to agree on that one. The time to evade is a bit ridiculous, and keeping it that long would only encourage users to DM cops in order to get killed so they can "get unwanted" more easily if they don't feel like waiting. It also cuts down on their ability to participate in other roleplays since it's not easy to end that one with so much time left, and it puts into question many other things when they are wanted that long...
From the side of the cops too, I would have to say that it's a bit annoying, and possibly an uneasy situation, when you come online or start work and find that the suspects on the loose have been evading for nearly an hour and you have to try to stop them, not knowing if it's because they are just that good at evading, or because no one else was available when they committed their crimes, which makes those cops question themselves at being able to arrest/kill them successfully, and if they should even bother trying or not.
