Intelligence is not a binary thing. There’s loads of people in academia that are very good at the specific thing they study but are absolute morons about near everything else. Just because someone has a degree in business or whatever that does not mean they know jack shit about geography.
Agreed, “to vague” just opens the door for abuse. Either for a zealous court to apply the law outside of what was intended or for a lenient court to let those who should be convicted slip through the cracks.
