To put it simply
Cops should value their life. That doesn't mean they have to drop there gear when kidnapped.
You roleplay well with me and come to an arrangement then I might be willing to drop some of my gear. If its crap then I am not going to just hand out free APD equipment. We have enough of that being given out by corrupt cops. I also enjoy trying to escape being kidnapped even if I have a very slim chance.
" Your being kidnapped we want your gear "
At this point, I am a bit annoyed so I begin planning my escape I decide to play the nice guy.
This will also be my decision as to if their roleplay begins to improve are they trying to negotiate with other cops or are they just being potato's wanting my gear.
" Drop all your gear on the floor and you can go "
Now I am like do I reward them for their tragic RP or do I a make an attempted escape and risk my life. So I decide to try an escape knowing I have a chance of dying whilst on duty. But these civilians could use my weapon to harm other officers so I am willing to take that risk
" Ok we are going to un-restrain you and don't move at all just place your gun on the ground " You will never take me Alive !!!!!!!!
The other alternative is to roleplay well talk with other cops negotiate the officer's release. The old days I remember all sorts being negotated. From Donuts, Spike strips, SUVs Various things. Even money if it isn't unrealistic. Usually, about $30k per hostage would be about right. If you roleplay well then depending on the officers you could be getting $30k richer for basically roleplaying doing nothing.
Disclaimer: Some cops may be really special and don't know how to roleplay themselves so it goes both ways
