"Jose Can You See"

I don't want to say too much about the immigrant migratory march today because my stance has always been the following:

"SHHHH, the business owners might be held accountable".

I do, however, have one question. I was stuck in traffic today watching this march in Florida. As you can imagine, Florida had quite a large amount of participants. My question is the following:

"Why so many flags from other countries?"

Take that as you will.
