Assault rifles need to be aimed or at least actively pointed in the direction of firing. The perp trying to kill a lot of people will not be looking behind him to see if a citizen is pulling his own gun. He'll be concentrating on where he is shooting. I may be ducking, but when the perp is looking the other way, I can easily put my laser sight on him and stop his rampage.

This is one of the better suggestions posted. I tend to keep slides to a minimum. Graphics are good when appropriate. I agree with "don't put up the slide and read it." What a turn-off not to mention an insult to anyone's intelligence. I do prefer color. Black and white is easy. Color holds attention. When making points, try presenting them in a way local people understand--pulling examples from day-to-day work that people can relate to. Humorous anecdotes work well. I really hate boring presentations. Don't tell jokes if you can't deliver them well. I once attended a presentation where the speaker was absolutely no good at joke-telling. He admitted that, but instead read us a poem--"Them Moose Goosers" by Mason Williams. It was unexpected and funny. Got us all in a good mood. Good luck!
