A better option would be to just not expose yourself at all to begin with. Strap explosives to a drone you plant ahead of time and kamikaze your target like they do to rusniggers in ukraine, you can hide in a bathroom stall and walk back out without anyone knowing you're the operator. Higher chance for failure if its broad daylight event with security lookouts, but thats why you dont do it ag an event. Do it at the man's home while he's in the backyard playing with his kids. The drone can fly right over the property line and you dont have to go anywhere near him. Shrimple.
