It’s actually super easy to pick most locks used on homes. I could teach a complete novice the basics in 15 minutes. It’s a scary thought, but on the other hand that means more people are being law abiding citizens and not breaking into your home.
…I should’ve been clearer, I work as private security as well as a consultations for designing secure architecture.
It’s just that old paradox of the best way to keep people out is knowing how to break in.
