If you've been in my class since the first of the year, I've told you about my experience at the mall this past December where a stranger was approaching me with his hands hidden in his pockets. After watching the DVD tonight, I'm certain I avoided what could have been a serious attack. His body posture, his direct line of approach, his hidden hands, the stare that I was getting... all very serious indicators that he was deciding whether or not I was going to be a victim. Luckily, I recognized that something was wrong and assertively acknowledged his presence, slightly turning my body to his approach, and verbally acknowledged him. It was enough, thankfully, for him to decide that I wasn't worth the possible cost of attacking.
If you're on the fence about whether or not to join the ACLDN, I really do recommend it. These DVDs (while not the most entertaining) are very informative. If you joined today, you'd get 7 DVDs. Couple that with the $5,000/$10,000 money for your defense and $85 a year doesn't seem too bad.
