This is exactly why due process exists. You can’t just walk up to someone, accuse them of a serious crime, and physically assault them without any legal authority. That’s not justice—it’s vigilantism, and it’s dangerous. If this person was truly there to meet a minor, then it’s a matter for law enforcement, not civilian “investigators” taking matters into their own hands. What they did could easily be considered battery and could open them up to both criminal charges and civil lawsuits. There’s a legal system in place for a reason—use it.
