Seen at The Alamo

Some of you have seen my "T-shirt seen at The Alamo" posts on Facebook. I post some of what I see people wearing, most of which are a laugh. However, being a Ranger on the 4-midnight shift, I see a lot of other things I don't post and I'd like to tell you about one.
Last night between 11 and midnight, I was up front, in front of the Alamo church. I saw a man and his wife, he was about my age. He stood before the Travis letter, took off his hat, knelt and bowed his head in prayer. When he was done, he stood at attention and saluted and walked off with his wife. I thanked him and he said "they" deserved it.
Not 30 minutes later a group of four, about 30 yrs old or so, who obviously had been drinking, stood on the same spot. One of the ladies started dancing. A jerky dance you'd see in a club. I approached them and said it was considered disrespectful to do such a thing on the grounds where so many had died. I did not tell her to stop. I was asking her to think.
One of the men said "He's serious", as if I was kidding.
Her answer was that she had ancestors who died there on both sides of the battle. I asked why she would do that, dance where they died.
Her answer - "Freedom".
I just shook my head. Another Ranger said "Freedom requires responsibility."
I wonder what her relatives would say about her actions. Would they agree with it as a type of celebration of their lives or would her dancing in that manner have been frowned on?
I think she knew she was wrong and, like so many do when they are caught in the wrong, she made up an excuse as to why she did it.
They left and even wished us a good evening.
I just don't see how her actions would be justified. You'd have had to seen how she danced and they context of the rest of their actions to conclude it was not a tribute to them, it was just thoughtless.
I don't see myself dancing at the place where a relative died. Our culture does not do that and I don't think hers does either. She said she was a local. I think she'd know better.
