Detroit family is much similar to a ndrina that a mob family.
The Detroit made man are tied by blood because most of them had married the other made men sister and cousins; this situation made very hard to flip if you're blood related. The second thing is that as you can see in the Giacalone Tocco families the son take the place of their father and so on.
Third the family traffickated in drugs but prefer the old mafia ways to make one ie loanshark,gambling ecc so you earn 10 but are free and enjoy it although that make 100 and stay in prison plus light sentences dont encourage rats because the only rat nove tocco flips in 2000 for avoid prison for drugs traffick.
Four the family had strong ties with the bikers where the bomp Bommarito at almost 90s was still respected in the detroit biker club and was more white collar that the other family.
All this thing made the family impenetrable by LE but made the family very small with only 30-40 made men.

I hope was clear.If you want I had a Detroit family chart.
