CMV: Police vehicles should not be allowed to be black with dark lettering

When police cars are black with dark lettering making it difficult to identify the car, to me, it says that police are not there to prevent crime but to catch people in the act of it. I have no issue with undercover police who are in completely unmarked vehicles, but a traffic cop sitting on the side of the road in a difficult to identify vehicle does nothing to stop people from speeding rather only to catch one of the drivers speeding or driving recklessly. 

In my mind police cars should be painted bright colors that clearly say I'm here, don't commit crime while I'm here.  Imagine a police officer sitting in a parking lot in an all black vehicle versus a brightly colored one. He could be sitting on his lunch break or writing up a report (or eating doughnuts) and if he was in a brightly colored vehicle it wouldn't matter if he was looking around to see if anybody was committing crime because citizens would know much more easily that police presence is in the area.

Edit 1: I think a common theme I am picking up from people who oppose my view is the assumption that people want to commit crime and would otherwise always commit crime if no law enforcement was around.  I'm operating under the assumption that I want to be protected from crime.  If a crime is to occur I want people to be around to protect me from it.  If police are brightly colored and their presence is known I am allowed to feel safer.  Not only do I feel safer but I would also feel a reduced need to commit crime in order to protect myself.

The problem is that the goal of the police is to minimize crime as a whole, not just when they are around. This is easier done with more subtle vehicles.

If cars are brightly colored, then you could easily check for them and, when none are around, commit a crime. With normal looking cars you never know if you are safe from the police. These less-visible cars can also easily be made visible with their lights.
