>>212819487 (OP)When the Yorkshire Ripper was terrorizing England, Scotland Yard and a gaggle of international experts came in to use cutting edge techniques to catch him. In the end, local cops just arrested everyone who visited prostitutes where he was active and caught the fag with the murder weapon. Ted Bundy was busted with a rape kit during a simple traffic stop. I just watched a podcast with one of the early FBI profilers.
>serial killers are abused as children. Except the one's who aren't. They always piss the bed or torture animals as kids. Except when they don't.All of the crime show CSI and profiler bullshit is 99% useless. These killers, at least in that period, are always caught by luck and competent police work. Just about the only effective addition are easily accessible databases (i.e., Gacy - who would have been caught much earlier if the local police could have googled him and found out he left Chicago because he was a violent rapist of teenage boys). Even now with violent criminals much easier to track and evidence even easier to access, like cell phone data, 40% of murders go unsolved because "too much work". Unless you shoot the CEO of a major company, they just won't try.
