Yes, sir, watch what you do...is right.
I don't condone the actions of the officers in the case, but one must consider the consequeces of their actions and how they're perceived when they send messages in any form (tattoos, etc.).
Police officers are not put in place for our protection, they could give a damn about the average citizen. They will kill you, if they feel that you're a threat to their getting home to their family that day.
Police officers will allow a hostage taker to terrorize their victims until the villain either runs out of ammo, or surrenders, as they will not put themselves in a potentially dangerous situation intentionally, ever.
These guys are code enforces who work for the insurance companies with IQ's around 100, which insures they never question authority (they do what they're told).
Please understand the mentallity we have to deal with when cops are involved. I refuse to call the police for anything that I can handle myself, as one could get dead, or have someone murdered when they get involved.
This is serious business...
