Why does the law treat different ages as an adult in different circumstances?

Question

I have a problem with the fact that you can be 18 and join the military fire weapons go to Iraq and get shot but you can't legally buy beer and alcohol

Then a teenager can't buy cigarettes, buy beer and alcohol, some can't get a license in some states, can't vote but CAN get charged as an "adult" for some crimes

Or this one an 18 and a 85yr old are okay but a 15 and 18 are bad yet the 15 and 18 are closer in age and are in the same high school in some circumstances

ju bored wondering LOL what do you think........

Answer 1

it appears to me that laws are m made in the moment...if we consider the bridge collapse of yesterday, Congress will feign concern, write a few bits of legislation, enact some new law concerning the structure of bridges throughout the United States, and then go back to their bragging about each other, and posturing before the cameras as they introduce "my good friend from Florida" or "my fellow Senator from California.
Whatever is expedient. Some of them don't even realize or are too darn lazy to look up the fact that some laws are outdated or unfair. That is unless one of them is caught driving while drunk ,,, and then all of a sudden he/she is in rehab and can't be touched by their laws.
They are so friggen phony.

Answer 2

It's the way politicians have drafted the rules....

It's not rational -- which is not surprising.
