The Baltimore "Don't Snitch Video" and this website both want to intimidate witnesses or informants. There are laws against this.
Official: Witness Intimidation a Crisis

BALTIMORECrime witnesses in this drug-plagued city are going into hidingnot only from the criminals, but from the police and the courts.
Afraid that drug dealers will kill them if they take the stand, an alarming number of witnesses in Baltimore are dropping out of sight, forcing authorities to find them, haul them into court and jail them in some cases to get them to testify.
Some witnesses lose their nerve after receiving threatening notes, phone calls, visits or dirty looks. Others get the message from seeing what has happened to other people who testified.
Its a sad state of affairs, said Baltimore States Attorney Patricia Jessamy.
