How to legislate (or enforce) against such things is tricky, this side of 100% perfect and unhackable driverless vehicle use. After just such an attack attempt on a UK airport, some years ago (and amongst various other incidents, accidents and ram-raiding of shops having added to the perceived need), there was a big programme in the UK of setting up strong bollards and/or semi-fixed concrete partitioning blocks at the boundaries of prominant pedestrianised areas and across buildings' glass fronts. (Although, from that actual incident, it seemed that the most effective counter-measure might be to have Glaswegian staff members on hand, everywhere... Even setting yourself on fire, isn't going to stop a Paisley baggage-handler from tackling you!) Some of the 'subtle but sturdy' open-area architectural street-furniture choices can actually enhance the look of a place, without looking at all like Czech Hedgehogs or Dragon's Teeth, and can often include seating and/or decorative planting.
There was also a string of terrorist attacks in the UK (and Europe too) of people driving onto pavements, into markets e.t.c. since cars are dangerous even on the best of days, and doubly dangerous when used so on purpose
Gov just set up guiderails, steel barriers filled with concrete and when a temporary event is held up (like a Christmas market) I kid you not there is a company that rents out these big old ugly concrete blocks they blockade the pavements with
EDIT: unrelated, geesh, LW hasn't been active since march. That's a long abscence, hope LW is okay.
I am back! I didn't even realise I had been gone for that long
Yeah, terrible news. My newspaper writes that the Chinese police said in a statement that the man did this out of anger over a judge's ruling in his divorce case.
The perpetrator tried to commit suicide after the deed with a knife, but police arrested him before he completely succeeded. He is in coma in a hospital so he cannot be questioned.
I often balk at how little it takes for someone to snap so extremely and randomly with murderous violence
