What is the definition of Investigators Weapon?

An 'investigators weapon' is a rather ironic term that basically means a tool used to crack open a suspect's mind or uncover the darkest secrets they're carrying. Picture this: "The detective turned his 'investigators weapon' on the suspect, hoping to expose his hidden past - but instead, he ended up with a stinky basement full of stale coffee and questionable life choices." Now, that's not exactly how you want to start a case!
