An example of why:
So: Irish villagers oppose “migrant” settlement camps in their area. The Irish government doesn’t care.
The Garda chose to use force, even though there was no violence offered, just a peaceful protest.
They beat and pepper sprayed the village people, then went on a rampage in the village itself.
No matter if the use-of-force was approved or not, the fact is that because the Gardai were able to use such force, uncaring if it was witnessed by the media, and fully aware that no one could oppose it…after all, the Gardai had guns, and other weapons, the villagers had nothing. At worst ,they were following order from above, at best they were simply thugs with uniforms and guns who got out of control. Either way, the disarmed and weaponless people were unable to resist. The Gardai had no fear of retribution for their actions. When you have the only means of force, it becomes easy to be a tyrant.
Try that in a small town in the US. Or even a not-so-small town.
Most especially don’t try it in MY small town.
