12 Angry Men: What argument does Juror Ten make for the guilt of the defendant? Is his argument fair and just?

He argues that the defendant is guilty.

Explanation:

No his argument is not fair and just. Juror #10 clearly has racist feelings from the beginning, as he states about the boy on trial in Act I, 'Look at the type of people they are - you know them.' This comment shows his assumption that all people similar in race or economic status to the boy are all inadequate members of society. He also assumes that people like the boy do not behave in a respectable manner or raise their kids well.
