For those who wonder how drugs wind up in the country’s jails, a bust in Nova Scotia on Friday could offer some clarity. Halifax Regional Police arrested a uniformed deputy sheriff, after intercepting him in the middle of an alleged drug deal outside a Dartmouth strip mall. The drugs, they say, were bound for the corrections system. The 40-year-old’s job involves courthouse security and escorting prisoners to and from jail. A 22-year-old woman was also arrested. The province’s justice minister says the bust “raises a concern,” but encouraged the public to “look at the positive”— “drugs were prevented from going into the institution. Apparently, the arrest of a deputy sheriff is the first of its kind.
