... if they get info but isnt creditable source they will take it to a creditable snitch who based on snitch in past has lead to search warrants that proved creditable
that way they can tell judge that signs warrant that he issued them based on guy before and turned out true
they go to snitch say "didnt u say joe blow grows pot at his house at 1600 Pennsylvania Avenue NW Washington, DC " wink and he will go oh hell yes i seen them nice plants
bam judge signs warrant you get door kicked in and when they find plants u can claim they lied and u didnt know snitch and join all others in prison claiming they were innocent
...
dead on, this is why they use snitches, they work
good(read dirty) cops always have some snitches in the back pocket - some low level drug arrest and didn't have the cash for the lawyer
if they suspect you, they can get you
here the move up food chain by getting low level guys and tell them u give me 3 people u walk then those 3 people lead to 9 more people and then well u get ideal
and then sometimes guys do it to make money or to be able to deal and not worry about law
like the case in texas years back snitch busted out 30 people differnet people then later they found out cops gave guy money to make buys he walk arounf corner pull his own rocks out and go back to give to cops and said yep she sold it to me. And some of people he busted never even knew guy and didnt sell drugs.
he game ran out when he got guy busted and turned out his dad was a president in naacp then shit blow up in cops faces and snitch got a shitload of charges
even for tampering with evidence
