I use LSPDFR Comes Alive, and it works. I believe it was updated for 0.4 as well. The events are random and I think it only targets them on your minimap and such when you are looking at the area when it takes place. I've had a situation with some lady doing a burnout and I think she was about to race another car, and another situation where a guy randomly started shooting some other guy on a sidewalk. You can change the settings in the files for how often they occur and such.
I'll probably have to use Stop the Ped for it's build in KeepCalm mechanic, it's one of the only plugins on this list I don't have installed.
