When they are in ghost mode, how are you able to harm them (you should be able to do that when they're near cops)
Also, you can no longer get healed as you get damage, so they have no reason to stay within you while you're being shot anyways, once they notice nothing happens, they'll eventually move away or go to bed when it's getting dark. I don't think there is need for this, but I won't just randomly downvote just because I see no use in it, just wanted to say my opinion.
