What about all the people who die from diesel particulates? Failing to consider that is exactly the mistake Europe is still making.

Particulates are easy to deal with using current technology--burn lean, burn hot (and inject lots of urea to get rid of all the NOx that this regime creates), and stick on a filter on the tailpipe to get rid of the stuff that does get created. The main problem is that diesel engines last forever, and a lot of old engines that don't meet requirements are still on the road.
This is partly true: You can reduce particulates, but they're still bad in areas with a lot of less-emitting vehicles. Also, the technology that reduces particulates needs to be carefully maintained to continue working as well as it did the day the vehicle left the factory... and there's plenty of incentive to cheat, in order to save money.
With 2016 diesel technology, the only "less-emitting vehicles" are EVs and possibly CNG-powered vehicles. As for cheating, as long as the manufacturer does its job (by either eliminating EGR altogether or installing a catch can in the PCV system), there is little to no incentive to cheat on the operator's part. Urea is dirt cheap as long as you don't buy from the dealership.
