There's more than one reason they might keep quiet:
1. They know the body count of those knowing too much about the Klintoons.
2. They may be waiting and hoping higher authority will take it on and do a bigger, better job of it.
3. They may be brainstorming how to do it and stay alive and have sufficient impact on the culture while getting it by the MSM who will not likely publish it.
4. They may have had their whole extended families threatened with extermination.
5. They may have given up feeling hopeless and helpless against the horrific tide of evil they uncovered and then realized it saturated the governments at every level.
Yea...sorry not buying that. I’m sure NYPD cops would’ve loved to bag Hillary. She isn’t a nice person and they all know it. If they had the goods on her, we’d have found out. Not every cop is a chickenshit about threats to them and if a bunch saw a video with Hillary diddling kids, we’d know. I’ll just say that with certainty.
