It's a little frightening how far a little knowledge and a few relatively inexpensive tools can go to undermine your security.
(LPL) is one of our favorite YouTube channels both because of the genuinely interesting lockpicking content, but also because of the way he explains things (and his sense of humor). While some people have argued that channels like these help empower thieves and robbers, the counterargument is that this knowledge can also be pretty handy in an emergency situation. Indeed, LPL actually even alludes to that himself towards the end of the video where he specifically mentions how the tool that he uses can be used by paramedics who are reporting to an emergency at a commercial property.
Ultimately, knowledge and tools are only as dangerous as the person wielding them. There are plenty of people who utilize knowledge like this to help upgrade security systems, become locksmiths, or even run successful YouTube channels about it.
