That ending was quite peaceful. Their disrespect for things of beauty, such as works of art in a renowned museum is really sad. Give them an ending such as the highway protesters that get drug off the road by their shirt collars.
I remember when, if you did something like that, they threw you out the door on your ass and the crowd cheered them on.
We were taught that there was a right time and place for everything and you showed respect for others or you might get your ass kicked. Worked very well. That is now gone. Boo hoo. Shakes fist at the sky!
