I don't think Moffat tiptoed around anything; it wouldn't have been worth viewing really.
No doubt Sherlock would have called Lestrade & had the bomb squad sent over to defuse the bomb & then have it taken for analysis. Get a squad to check that the gunmen had gone & look for traces of anything left behind as they would have to declare the pool area safe for use again; then off home so John could blog it & Sherlock could enter the data into his 'computer'.
Boring police & detective legwork' really.

Mycroft’s popularity doesn’t surprise me at all. He is, after all, incredibly beautiful, clever and well-dressed. And beautiful. Did I mention that?
