Our youngest gave first aid to a guy knocked over outside the AECC on Monday night after the Blink 182 concert.

When they paramedics arrived they thanked him and told him to move along - no name, address, whatever. He may, just possibly, have saved a life, but if he had done something wrong they would have no way to find him.

Circumstances vary so people shouldn't be afraid to use whatever knowledge they have to try and help, eg getting someone out of a burning car, but otherwise keeping them still etc
