Drugs bust in Jerusalem Street

On Friday a house was raided in Jerusalen Street. £5000 of drugs was siezed and a 20 year old man was arrested and charged.
One could argue that this is the reason for the massive undercover and uniformed presence. However this ignores a number of issues.:-

1.The stated agenda of protecting property.

2.The presence of a large subculture of heroin addiction in the Holylands/Botanic area so large that a needle exchange has been set up. No heroin was siezed.

3.The large number of drug dealers in the Holylands/Botanic area.If they'd wanted to, the cops could have raided ten houses and siezed £50,000 of drugs

The raid appears to be cosmetic, a bit like the attemps to "police" the "students" in the Holylands
