gsr and prints are top-tier forensic markers. you want to eliminate them as much as possible, to the point where if you're making explosives in a small lab in a trailer for use in bombs, you never ever want to be on the site without two layers of nitrile gloves. never ever leave a weak link in the chain of evidence. there will be evidence, you never ever wanna be associated with that evidence. also for example, you wear cheap cotton clothing you can burn in a barrel each time you use a lab to make drugs or explosives because your clothing will pick up chemicals, and you can't wash these chemicals out in a washing machine at home. trace evidence is a massive achilles heel. never commit crimes and you don't have to worry, of course. crime is wrong and bad.
