I can’t personally think of any case where LE knowingly let a murderer remain free when there was PC to arrest, just so they could continue to build their case. They can do that while he sits in jail. But I’ll take your word that it’s happened (idk about MANY times though). Based on this logic, you’re saying you wouldn’t consider someone that murdered a mother and 2 children “a threat”? And considering his wealth, I’d also consider him a flight risk. If LE thinks he did it, and they have enough evidence for PC to arrest, I think he’s exactly the type of person you wouldn’t want to leave on the streets while you gather additional evidence. Especially with the public in such a tizzy. JMO. PC to arrest is a pretty low standard, and I think an alibi that wasn’t checking out whatsoever (which is how Sheriff made it sound) plus the other surrounding circumstances that made everyone suspicious from the beginning, plus the insistence of abuse by friends, would give them PC. MOO.
