I honestly don't think that terrorists targets include residential areas....forgive me BJ as I don't know where you live.
They hit high profile targets and really nothing else.
I can understand the concern but to be honest I would have ignored it and if it hadn't been collected by the next day it would have gone beside my bin.
Living where I do we were very aware of the IRA, not as a target but because of sympathisers. The issues between religions is endemic in my part of the world.
When my hubby moved to Scotland he simply didn't get it. To be honest he still doesn't.
Our schools were segregated, our housing estates. They even had different times when the schools came out to avoid fights. The children didn't understand what they were fighting over but they fought none the less.
There were some scary times in my part of the world and I stay in the back end of nowhere
