Ok before everyone chimes in and says "there's a rat openly walking around NYC " etc which is proof the mob don't go after rats anymore

That's because of the heat it brings/ going after someone supposedly under federal
Protection (well yes they left the program so technically not) but they're still a government witness. So that would bring heat- we know

Now how about a guy like Gotti jr

He self admittedly in his book ratted on Marino & Joe Watts

He didn't go all the way hence was never a federal witness. Hence a half rat

Do they still whack half rats. He's isnt safe as a full fledged turncoat
