Satire

 Satire is irony humor,  sarcasm to expose stupidity and vices with the intent of improving social condition.

The first picture is a satire because its criticizing two different groups whites and browns. I know this  because the policeman is speaking English and the prisoners are Mexican because they are speaking Spanish and they don't understand what the policemen says.

The second picture is satire because its judging someone by the way they look they are stereotyping them.  For example, he is using his phone and they are judging him by saying that he is a drug dealer only because he is speaking on the phone; so this is satire because its stereotyping but also has the sense of humor by bringing up the stupidest ideas.

The last picture is satire because its dividing the border the United States and Mexico and the Mexican man, is all armed and the American guy  is asking for help. In addition this picture has humor because in real life is usually Mexico asking the USA for help.
