The three kids and their moms decided to take this to court as they believed it was going against the 1st Amendment.
It is decided that the students have won this case. Their statement did not hurt anyone or distract them from their studies. This means that they can display their opinions publicly as they did. They have this right under the 1st Amendment.
Throughout many more cases, this was brought up. For example, school attire. Kids can wear what thy wantup to an extent.
