Helicopter can also go into autorotation mode, i.e., to "gently" land even with engine failure. I think airships has no moving parts, what's safe, and with the gas leak, I think it is rather slow process, so it would be easy to gently land.
Of course – fully agreed that something has to be done. Civilized countries, like Netherlands have "sound traps" – if a vehicle is too loud, photo is taken as in speed photo traps, and penalty is sent to the owner. Sadly, I do not live in such a country.

Helium could be detected with some specialized detectors, but I suppose approximately -- so, as you said, finding exact leak place is challenging.
