An online columnist is using the student reaction to the shooting at the Florida high school to raise the question of whether the voting age should be lowered from 18 to 16.

Harvard law professor Laurence Tribe is using the “#Children’sCrusade” that resulted from the shooting to also argue for lowering the voting age to 16.

But President Trump says perhaps the age at which one is allowed to purchase assault weapons should be raised to 21, even though 17-year-olds may enlist in the military and be required to shoot assault weapons. The Florida high school shooter is 19.

On the other hand, scientists say the brain is not fully mature until age 25.

You can’t serve in the House of Representative until age 25, in the Senate until age 30 and serve as president until 35.

When the 26th Amendment lowering the voting age to 18 was passed in 1971 during the Vietnam War, when 18-year-olds were being drafted, the slogan was: “Old enough to fight, old enough to vote.”

So here we are arguing again about when people are mature enough to do certain things. If the brain is not mature until 25 and one can’t serve in Congress until 25, perhaps we should raise the voting age and the right to buy guns to 25, right?
