When guns are banned, then people will find other ways to kill other people.

I’d consider that along the same lines as acid attacks and consider THAT community first, before the Russians.

I’d think that is the Russians were going to off someone, they would not do it in such a way as to be so obvious that it was them.

The Russians poisoned a double agent and his daughter in the same area just a few months ago. They wanted it to be obvious, pour encourager les autres.

It's likely this is related, possibly accidental, unless there's more to the deceased lady and her husband than is being said.
