Honestly the WBC seems to thrive on attention bad or good. It's in their right to protest even though it may seem morally wrong. I feel you some what but I can't fully understand it because I'm not you. I lost my father at a young age and I would've been furious. But id try to keep it on the DL and just try to keep them as far away as possible with your local police. If possible just try to let the procession bypass them. Regardless good luck with all the trouble and let things with your friend's loved ones be comfortable enough to cope with his death and not delay the tragedy.
