woody: "the copper who told me this said give me organised criminals at least you know what your dealing with the disorganised ones are way more scary"
The copper knows his business. At least as important from his perspective is that the organized criminal knows what he is dealing with. He knows how arrest, booking and bail goes. He already has a lawyer, and if his can't do the case for reasons of ethical or scheduling conflict or inexperience, his associates can get him another. He knows what to expect from jail, and what not to expect. He knows about how much his bail will be, and how to raise it. He knows he won't get raped in jail. Maybe someone else might, but he won't. He knows his girl won't leave him. He knows he won't lose his job. For the disorganized criminal, all of these are risks and unknowns. He has fallen into a world of trouble, and he is far more likely to run a high speed chase or to put up a fight -- maybe even a suicidal fight with lethal weapons.
