Sorry to keep harping on about France, but we've had our share too.https://en.wikipedia.org/wiki/List_of_terrorist_incidents_in_France
Last year, after the Nice attack, the policing of schools, festivals concerts etc was increased. Sometimes the Army replaced the police.
Near us, in a tiny market town, we have a country Music festival every July, and last year there were armed police checks on all vehicles moving round the area.
There are 2 branches of police here, one more for civilian jobs, and the other militarised (Gendarmerie.)
