I think that the serving of the warrant against Stone was proper because I think that he would have attempted to destroy evidence if he had been given a warning in advance. He already had self-identified as a "dirty trickster." Releasing him later is fine AFTER law enforcement was through going over his house. Getting him under control first prevented him from hitting the "delete" button and/or burning valuable documents.
You believe it's proper because you're a Trump hating douchebag, and for no other reason. If they had executed him on the spot, you have have approved of it. There is no violation of our Constitutional rights you wouldn't approve of so long as Republicans are the victims.
There was no violation of anyone's constitution rights. Don't you know anything about standard operating procedure? Are you really the same age as your avatar? Would you approve of a wanted individual being given time to destroy evidence?
Oh, gee. Call a drug dealer and tell him that you are coming to arrest him, but give him time to flush his drugs down the toilet. Grow up.
