WeatherHost,
You bring up a very good point. However, how many storm chasers are truly employed by the NWS or the local EMO? Many storm chasers have academic affliations (i.e. university/earth science) or SkyWarn affiliations? And again, what violation was he arrested for? Other observers stated he was not blocking any roads nor interfering with any emegency response units so that brings up the validity of the arrest charges.
Just MHO,
Jim
