I did but am not convinced, I always remember a work colleague in my last job before retirement who had a masters degree in Criminal Psychology, she was having a debate with another colleague around the death sentence, she said she did her dissertation on the death sentence in some US states, looking at states that had introduced it and other states that had stopped it, it turns out (according to her) that the statistics often show that states that dropped it had reductions in Murder and some that introduced it had increased rates, I think she was looking at the 60's through to the 80's, she certainly appeared to know what she was talking about.
