"A drink or two does not suddenly transform a person."
Actually, would you agree with me that that would depend on the individual? Some can hold their liquor better and drink quite a bit and they are fine. Yet others, you give them one, JUST ONE drink, and they already feel the effects. These "effects" hamper judgement and reaction.

"a cop having a beer or a glass of wine is not related to bad law enforcement."
No it's not, but it is related to a possible bad and/or slow possible life saving decision. It could affect the officer's patience with a suspect, which could lead to the officer going overboard. As it could lead to a delayed reaction and bad motor skills where the officer just failed to save his partners life in a fire fight, where the outcome would have been different otherwise.

Some points to consider.
