What he's doing is similar to suicide by cop. They not gonna lock him up simply for saying this but he's probably hoping someone takes an interest in reopening the case...
You can talk about shyt you've done without endangering you're freedom, but that's not what he's doing...
For people saying why would he let an innocent man go down for a killing, look. I've spoken on this before---->I had a homeboy go down for shooting someone I shot before, ironically this was also in 2010. My homeboy sat in county for about a year before they dropped the charges on him...
I was investigated for that shyt until like 2013. I never had an inclination to run down and say "ay this guy didn't do it", #1 that's just not how that shyt works. And the guy they arrested for it was out doing his dirt in the streets as well, we all know there's a variety of consequences that come from that lifestyle and this is one of them, you can get roped into a charge for something you didn't do. It happens...
More importantly, there are people who are paid to go and solve these cases. It's not mine or any other regular citizen's job to solve that case for them...
I also lost 7 months once behind getting arrested and convicted for someone else's shyt. This case was less serious, it was a b&e, I picked some cats up once who robbed this dude's recording studio, stole all his equipment. I got charged for it, convicted with a 6-8 month sentence, did 7, never thought about saying "well these nikkas over here did it". shyt like this happens across all levels of crime, people get arrested and/or convicted for shyt they didn't do...
