No. It is a big problem and it is going to get worse before it gets better because it is hard to catch them and prosecute them. People don't want to testify.
It is like the terrorism. It will get worse until we get good at fighting it. But our police are trying.
That's the problem, we need the Marines, not the police to take care of this problem.
Rudy Giulinai reduced crime and the murder rate in NYC by dramatic levels - not through "prosecution" and "testimony" - but with aggressive policing. the police are not on offense in these sleepy suburbs like Fairfax and Nassau County. if you call them, they come and take the report, otherwise they write traffic tickets all day for the most part.
you need aggressive policing to make a dent in this - shake em down, bust them, stop them in the street and frisk them, and if they pull a gun - shoot a couple of them.
I would say that in that sense, your Northern Virginia, just as the other communities mentioned in this thread, will continue to suffer even more illegal immigrant violence by former Central American paramilitaries now operating on US soil, such as Mara Salvatrucha, despite 'how hard the police work'. And that is unfair to both the police and the citizenry.
