Having an impromptu parade is okay, but dealing meth and heroin is strictly a no-no:

Narcotics, Warrant Arrest:
On March 16th at 4:23 pm, officers patrolling in the area of 22nd and Tennessee spotted a subject walking in the area that they recognized. They knew that the subject had a felony warrant for his arrest for a probation violation. The suspect initially refused to comply with the officers’ orders to stop and continued walking until one of the officers ran ahead of him and cut him off, placing him under arrest. During his search, officers discovered nearly 9 grams of methamphetamine, 1.2 grams of heroin, and some marijuana inside the suspect’s jacket pocket. Due to the amount of methamphetamine found, coupled with the absence of any ingestion devices, it was believed that the suspect was selling the narcotic. He was booked on the methamphetamine for sale, heroin possession, and his no bail parole violation warrant at Bayview Station. (SFPD Case No. 120216254)

Stick to salted caramel chocolates, folks.
