He was close to home, would they let him change there? And if he did could he have washed down in the sink, or is that a big no no? Trying to make sense of why it appears there is no blood on him or his clothes in the video (other then his pants being on fire from lying)
That would be a really big no no, when they collect clothes for evidence it has to be done in a specific fashion, Just like when you have to collect clothing after a sexual assault. Unless they had the kit with them when they were at the scene then they could not have let him go home to change or clean up, and that would have been another gaffe, since they are supposed to photograph while the person is still wearing the clothes first.
