There's an oxymoron in your sentence. Let's see if you can identify it on your own.
First, way to stick to the topic at hand. Can't respond with logic and reason...so you attack grammar? Wow, that's weak.
Secondly, there is not an oxymoron in my sentence. Oxymoron - a figure of speech by which a locution produces an incongruous, seemingly self-contradictory effect, as in “cruel kindness” or “to make haste slowly.”
Tactical shooting is a well recognized category of firearms training. It stands in contrast to non-tactical or target shooting. Competitions that center around tactical shooting and the competitors that compete in those matches are not contradictory to the weak ass training provided to cops...which is akin to target practice.
My point is clear and accurate. You can continue with red herrings if that's your thing.
