about the monstrance in the crowd

[grotto]

Does anyone have a suggestion about what to do when encountering a person who is rather "overzealous" in a crowd where you really do not want to make a scene for the media but the situation warrants attention??????? I wrote about the man in the crowd in front of Terri's hospice holding up a monstrance as in adoration - the place for the Eucharist was not empty but what it had I can't be sure - it was an "off-white" in color. So! I was very perplexed - I felt moved to not allow this - I didn't know if I should "take it from him" - no, not a good idea - anyhow what if it was the Holy Eucharist that he had taken from a tabernacle somewhere? What would a priest have to do about that ? As it was, the good priest that was summoned and tried to converse with him wasn't really able to correct the situation.
Like I said, the news media was all over the place and some of the nearby people didn't want me to keep telling the guy that he couldn't be doing what he was doing (he clearly was not a priest, nor was anything else right about this) - they were afraid it would be meat for the lions that the Catholics were fighting amongst themselves. I can understand that. So, what is your advice when
something like this happens - sacreligious for sure but what needs to be done? Believe me, I need this kind of advice because I sure do run into off-the-wall situations. Anyone?
