Bruh it wasn't just an accident. This was the presidential motorcade and secret service. Literally everybody in a 10-block radius knew who was there, and whether they had permission to be there.
This person drove their car into the motorcade, and then kept going. Secret service's job is to protect the president, and as far as anybody knew, this was someone after the president. They weren't harassing some idiot that was driving drunk, they were pursuing and engaging a very real potential threat to the leader of the nation.
I like how through these comments, you've called other users "stupid Americans" and you don't even know anything about the event in question. Good job kid.
