I am not the police, not even close. I just know that in any profession, we develop intuition that is probably based on own experience. But once in a blue moon, there comes the situation that is so rare, maybe 1/2 line in textbooks, and it defies all experience, it can later get into articles and maybe become the first one published. But with these situations, intuition is silent. I saw it, once, and several specialists were profoundly mistaken, because it was a rarity among all rarities.
What if this is such case for the LE? Well-planned, random, no witnesses, no electronic traces. Little DNA. Contaminated scene. The plan and the retreat have been made well in advance.
And if you look at Carroll County police department FB, their average cases are psychotic meth heads shooting fireworks from their cars, abandoned animals, fights, cooking some crazy brews. They deal with it. They have experience and know the people. And then, something like this comes along. And they are making mistakes, for sure. But maybe it is above everyone’s head?
ETA: why does Britain have cameras everywhere, and we don’t? Money issue? Or just laziness?
(Seriously, get on their page and look at the faces of their usual clientelle... we should have a thread about the drug problem because it is killing everything around.)
