If you were a time traveler would you identify yourself?
You would be mad.. First you would have your machine confiscated and then they'd put you in a padded cell for the rest of your life.
What would happen Snake, is that the government scientists would be waiting for the time-machine to appear and then it would be re-programmed to be teleported into the Sun....Doing that would save the government and our country from having to pay to keep the time-traveller in a padded cell for the rest of his life

..
I got that idea from an episode of Torchwood, whereby Captain Jack teleported a beautiful murderous alien and her time-machine into the Sun
