I surmised, based on his record, that there was a warrant involved, but haven’t seen the reports. Do you happen to have a source at hand?
The driver’s family stated so in an interview the other day. It is one of the many youtubes from the news casts that are on youtube now showing the shooting vid.
There have been several other reports since, but I do not remember where I read them (BBC report may be one of them).
