I was surprised at the Roddie charge myself. What we have seen so far doesn't seem to me to justify a felony charge. However, the police have seen more. It may very well be that he used his car as a deadly weapon in a threatening manner.
Why were you surprised? From the initial statement according to McMichae1 (sic) he was as involved as they were - from the police report:
"....McMichae1 stated the unidentified male turned around and began running back the direction from which he came and " Roddy" attempted to block him which was unsuccessful.... "
