Anyway, on the subject of heads and bullets, there is one undeniably real video of a person actually being shot in the head: R. Budd Dwyer's last speech and on-air suicide in 1987. I won't post it here out of respect for everybody's lunch, but it's easy to find online and has been something of a meme in certain internet gutters. And it doesn't look like anything I've seen in a movie or video game, even one striving for realism.
I wondered of @Exif's question about did he really get shot in the head was even worth responding to. You can clearly see the gunman run up and point his gun at the officers head point blank and shoot...and officer immediately goes limp.
Alas, there are way too many videos of executions (not all beheadings- many shots to the head at close range) floating around the 'net these days with ISIS and their trusty smartphones and PR machine if one needs similar examples.
