i dont thhink i have a brain smart enough to commit a murder that would be near impossible to solve or gives people a hard to to solve. if i commit a murder, i'd be found out at most within 1 day.
If I were to consider it I'd inform myself as much as possible and think of as many possibilities as possible.
Though I'd no idea what that would be like, my only experience with that are TV shows like Scandal and HTGAWM.
That being said, I might be smart enough to inform myself properly, but in no way would I ever have the stomach to pull it off.
I've watched waaaaaay too many cop and medical shows, and I can still say no. From what I've seen/ read, experience is really the only thing that allows killers to get away with what they do. I think for the average murder, people make something like 14 mistakes that end up getting them caught, where experienced killers know what mistakes not to make because they've been doing it for so long.
