Well... Obviously I picked the lawyer route but ya kinda have to do your time in that arena before you get to the cool smashing gavel job.
Also, I have waaay too much ADHD to sit in one spot trying to keep a solemn expression on my face. I would refuse to wear those ugly gigantic robes. I'm sorry, but i don't get all dressed up in the morning just to go cover up in a mumu and sweat all day. I'd be cruising around the intrawebz under the bench.. Texting, reading articles about the top ten tooth brushes of the year, stalking the forum, practicing how to use a Bluetooth ear piece without moving my lips when I talk. Oh yeah, and I need bathroom breaks every twenty minutes.
Also, I'd be asked to step down before finishing my first day. Why? I simply cannot control my 'omfg you're an asshat moan'; rolling my eyes at the ridiculous lawyer tactics; rolling my eyes and sighing loudly and dramatically at pretty much everything going on; slamming my head down and exclaiming that we just need to end this potential two month case now because I already know the verdict; outloud laughing and guffaws at horrible witnesses; slapping a defendant, who came to try prove their innocence and avoid lock up, up against the back of their head for wearing a sweat stained old saggy t-shirt and dirty pants; taking hair clippers to said defendants to rid the world of mullets; strangling experts called in who take up to five days explaining how it was proven that the bloody knife found in the hands of the killer was the murder weapon.
Also, I love defending implicated individuals. Pays good too.
