Immigrants vs Tear gas

In class today we listened to more of the podcast on migration. The podcast was definetley biased against Trump as they used information about how he is hurting the migrants. For example they talked about how border officials used tear gas in order to make migrants settle down. Honestly I'm glad they did that. The migrants attacked the border officials so the border officials fought back. What are we supposed to just let them throw rocks at us? Then when we fight back are we supposed to feel sad or ashamed that we did? NO the migrants attacked us first and its not like the tear gas killed anyone. I am sorry, but if you want to be violent like that then face the consequences and don't act like we should feel sorry for you.
