These people are Canadians. They don't have a right to come to the United States. It is a privilege, just like it is a privilege for us to visit Canada.
Got a funny story for you though. There is an fired RCMP officer that keeps threatening people and law enforcement in my local area. He was allowed to cross for a hearing regarding a no contact order being requested against him. When the hearing was over the judge granted the no contact order. The Canadian threatened the requester and was arrested on the spot.
I agree that the Canadian has no civilian rights in our country, but I really do hope and pray that you realize, that this is a bigger issue.
The second agent just wanted to let the guy go. Sure, the Canadian should have shut his mouth, but the first agent should have never tried to make the Canadian’s life worse just to exercise his power, which is exactly what the man did.
This problem is systemic, if you don’t know that, I pray you wake up before it further reaches you or someone you love. Tyranny is rampant, don’t think Border Patrol is somehow off the hook. I assure you, they are a part. Most patriots would be frustrated instantly, these people aren;t their for the good of the country, they’re there for the paychecks. That’s the problem.
