No several police departments do not say he is. No. No reliable information says he is.
Which police department other than the one you posted from Prince Georges say he is? Name them. Then provide the evidence showing he is MS-13. The only thing the government has is he was picked up in a Home Depot parking lot with several other people and an informant told a police officer that he is MS-13. He was not arrested at that time. Just questioned and released
They claim because he was wearing a Chicago bulls hat he was a gang member. That is not evidence and the court said as much.
Provide your evidence of him being charged with a crime. We will quickly find out you have none. Making up shit doesn't make it true.
