posts have been wasted on the fact that the Mafia is no longer what it once was because of the rats, etc., but in other criminal organizations such as the Irish mafia,the black and latino oc,the bikers ecc

I don't know anybody else.

BMF had around 100 informants.
Craig Petites Enterprise had around half a dozen.
G.Ds had 263 informants during Operation Headache in 1995.

But the groups with the least amount that I know of is:

Black Souls, Not too much information on this street organization and a handful of cases on them. Not too many informants from them. Ratio wise could be on par with Genovese Family.

Mickey Cobras, Somewhat to my knowledge.

Black Guerrilla Family in California, Barely any new info on their activities on the street, no major cases, no documentaries on them, few articles on members interview, same old repeated info on net, secretive as can be.

Baltimore branch had somewhere around a handful of informants (the ones that haven't been killed) and more to come in the future.

the black souls don't have many informants because they don't have many members

the mc's had snitches back in the 90s

that's how they fell apart and they've always been a small mob

Black family- I hear more these days about other black street gangs than the bloods or crips. Are those two losing power/size to other new gangs???

@ Cookcounty ,
Whose smaller between the Souls & Cobras? By the way, haven't the MC's always been small? They still have a strong grip in the low ends despite those 2 major indictments.

@ Bigboy,

It depends on which other black gangs your hearing about. They are applying that term to even local crews in some cities; New Orleans, Philly, NYC, etc. I say this because most of the crews don't have traditional gang culture (colors, hand signs , logos, handshakes, other identifiers).
By the latest gang report have stated the Bloods umbrella have been the most expansive group. They have absorb some local crews , Surenos are next, then the Crips umbrella. Out of Chicago are the GDs (obviously) , VLs, & Stones, but their on low end (VLs & Stones) of the percentage chart.

The bloods and crips can't be described as united gangs. There are hundreds of different sets and the only thing that makes them bloods or crips is the colors and them naming themselves as such. Different sets of crips might be working together or fighting each other.

@blackfamily

the cobrastones weren't small but the mickey cobras have been medium size to small now

the only thing i know about the black souls is they're a tightknit westside mob

All of the criminal organizations have informants but many of these informants fall into many spectrum or categories. For, example in Mexico the cartels use snitching as a weapon. Some times the "estacas"(cell of 5-6 emforcers) and their commadantes(captains, local bosses etc.), have the Marines number on their cell phones to call the authorities to either snitch on a rivals hideouts or rival commadantes etc. or sometimes use them in a shootouts so they' can eliminate their rivals. The Golfos from Camargo were using the Marines to kill Zetas that were making an incursion into town or challenge each other via radios they carry into clashes or "topomes" in the middle of town many times. Both sides play a very dirty rode but the Golfos are more likely to use the army or marines as an indirect weapon. All cartels have informants inside the police to either advice them on army, federal police, and marines units around tone to know exactly where they are at all times plus hundreds of "halcones" or street guys reporting info about mainly army and marines units but also suspicious vehicles or people. Them you have snitched like Z-40 that co operated with the DEA to give out I of about the regional bosses to consolidate power within the Los Zetas group or Vicentilo being am DEA informant and I form on rivals to give him temporarily immunity to pass drugs etc. All organizations have snitches, there is no criminal organization that doesn't have.
