Didn't read the whole thread - but my two cents worth....
If they are tasteful and not facial tattoos I don't see the problem. Where do we draw line? In this day and age we need to be able to accept pretty much anything, tattoos have been around for a very long time, let's keep them around for alot longer.
Personally if I got pulled up or arrested, tats on a cop would be the very last thing I would be worrying about, equally if I needed to talk to the police for any other reason, again tats would not prevail my thoughts.
