Jessica's First Christmas - S2-E7
Revealing mistake: At the final rehearsal for the church nativity play when Betty first comes on stage with baby Jessica wrapped up in a blanket and places her in the manger, it is obvious that Jessica is actually a doll.
Suggested correction: Not true. Generally they are tasting it to see how pure the drug is. Hard drugs are often diluted with milk sugar, so they make a bigger profit. The higher the sweet taste, the less pure the drug is.

First, law enforcement officers don't ever taste drugs, it's a good way to die if you don't know what you're ingesting. But second, the mistake isn't saying they are tasting drugs to know it's strength or purity. The mistake is explicitly about a cop tasting a drug and positively identifying what it is based on taste, which happens a lot in cop movies. Such as when the cop says "that's cocaine", not "that's half pure cocaine."
