As each incident is raised to high level overview scrutiny, the prosecution costs rise and the efforts are tied up in prosecution. If they flood our courts with high profile cases, then they can overload our system and overburden our taxpayers.
They also play off of the "innocent until proven guilty", "we want to be released until the trial date is set", etc.. They are in our country illegally, not being evicted by an INS that was politicized.
Even the Christian edict of "turn the other cheek" could spell out our doom.
They know this and see it all as a sign of weakness.
And here you have a dilemma I have wrestled with, as taken to an extreme, it could spell the doom of Christianity as well. And almost did, in the past, with the rise of the Ottoman empire.
Perhaps they don't realize God only endowed us with two cheeks. Personally, my patience has ended.
