Montgomery County is a county full of rich people and those that serve them. If you don't like policing in such a place, you should either get a job in Fred-neck county where you likely live or just put up with it.
Illegal immigration is a problem, and the pols in Montgomery and every other country should deputize the police to make arrests for immigration violations. Nevertheless, the Police SERVE THE COUNTY that pays their salary. If the county wants them to make nice with "beaners", they better learn how to deal with it, instead of whining like a bunch of beer bellied yobs on a bulleting board.
A little local history:
30+ years ago, tranquil and prosperous Montgomery County was a cush job for county police, certainly when compared to adjacent Prince George's County, which was awash in racial tensions and criminality pouring out of Northeast DC.
Even Takoma Park which is directly adjacent to NE DC and is also in Montgomery County remained quiet, pleasant and sedate. From top to bottom, Mongomery County was an easy job to police, and you could tell it when you were pulled-over for a broken taillamp and treated with respect (even to us teenagers back then)
Flip to now, and the county is awash (like everywhere else) in illegal aliens, who BTW have completely subsumed Takoma Park. "No hablo Ingles".
It's a completely different world for Montgomery County LEO's, even as the ultra-liberal denizens of the county are trying madly to keep their eyes wide shut to their exploding illegal alien problem.
