This talk will take you through the basics of how to pick, rake, bump, impression and bypass a lock, but be careful, you're leaving a lot of evidence behind. Using datagram's work at lockpickingforensics.com as a jumping off point we'll explore how a picker gets in, and how, with careful observation and some practice, we can uncover their method of entry. Using macro photography, illustrations and a few anecdotes I'll give you a basic education in several entry techniques and a primer in lock forensics.
