I disagree. For every German soldier killed by one of these, the Germans would kill 400 local citizens to make an example. A lot of innocent people who would have otherwise lived died because of locals taking pop shots at German soldiers. The entire French village of Oradour-sur-Glane was wiped out like this:

The whole "French Resistance" is a myth. Maybe 10% at most read the resistance newspapers. Most understood it's not worth it and chose to live.
There were a lot of sorry pieces of shit in the colonies that felt the same way about the British.
Thank God the pussies didn't prevail back then.
