I was checking some TI videos and I found a very interesting one, as it's the usual "shoplifting" street theater or "robber" street theater many TIs experience. The security guards or store employees gets "warned" by the sub-human perps and the harassment gets shifted into a legitimate authority, while the real criminals roam around or actually leave the store.
Considering many stores promote the idea of reporting unusual behavior, this is useful tool for harassment. I'm actually impressed by this video and the idea of recording every perp hired by these sub-humans to roam around the store, contact security guards or report unusual behavior to the store employees. My only opinion is that this TI is very smart to gather harassment evidence.
General advice should be, buy a bodycam ASAP.
