With respect to Belmont, robbery motive is absurd, given the circumstances.

You're going to be waiting at / near the guy's house, sun going down but still broad daylight on a clear early evening for a heist like that? With unknown # cameras / witnessses?

More likely 'robbery' motive is either decoy or coincidence.

if the former the question becomes who at L&B or among co-owners intimates tipped the robber / shooter tipped off?

Also Q: what aspect of the 'robbery' went 'wrong'?

There might be more details to come but so far nothing has suggested a 'struggle'.

Curious to see if any camera images come up. If it as it appears it was pro shooter, there's zero chance he went to Staten Island, far better to get on Belt / Gowanus despite backups, zig-zag and then... get the car chopped?

But that's pure speculation. Maybe things were sloppier than they appear and we'll learn more.
