The picture of the cop is a disgrace and judging by his tats his motive as to naming his dog Rommel seems pretty clear.
Rommel was not a Nazi however, but a member of the German officer core and a veteran from WW1, and those jewish slaves you're talking about Hitler had ordered killed, but Rommel refused to obey the order, which could have gotten him killed if Hitler found out.
Again I'm not defending the copper in the least, there are other parts of Rommels story that put him in a less favorable light and I could discuss that in depth but this has come a long way from the 49'ers back up QB.
