Well, the obvious difference being that it's pretty difficult to kill 17 people with a knife. Let alone get into the 50's like the old guy in Vegas did.
85 people were recently killed in the UK with a truck in less than 5 minutes
Google it for yourself
We need to stop bad people. Not bad objects. Are we going to eliminate cars & trucks next?
I think you are referring to France, Monsieur. The Promenade des Anglais. Pretty sure that would be considered a major terrorist event if it happened in the UK, and I haven't heard of it (though there are bombings in the ME that kill in the hundreds and we don't even bat an eye).
Cars and trucks are necessary for transportation, which allows us to go to work, among other things. Without them, many people's lives would be almost unworkable. You don't really need guns, outside of a few environments/professions. They're largely for recreation and sport.
And if we had functioning teleportation devices operational, hell yeah I'd be down to FURTHER limit vehicular operation.
