Let's examine this "professional courtesy"...

- A dirty cop parked at a fire hydrant.
- No ticket from the local precinct.
- Everybody in the neighborhood sees the cops breaking the law in broad daylight.
- It is clear to everybody there is no professionalism in the precinct!

So, the cop from another precinct comes into this precinct and makes all the officers here look bad... and they call that "courtesy"??? They stick up for the guy making them look bad because he's lazy?

How about they try a little more intelligent model:
The officers who come into somebody else's precinct obey the law and help their fellow officers look good?!

Come on folks. Just a little common sense!
