Yeah, but in general the mentality towards killing ppl has changed, right? That list is extremely small, compared to how long it was once.
For example i can't really imagine a US-american Family to fight a war as bloody as the one in Canada anymore.

Excessive murder is what frightens ppl, either of prison or for their own life, and the reachthrough against killings (mandatory life for example) has IMO greatly contributed to so many mob guys ratting out against their familys.

For example, if there is a dispute between the families, that would have been settled by whacking a wiseguy with a probability of 90% in the old days, has now probably a chance of 10% at most.

Can you say that?
