Exactly. Courts are only as impartial as the officers and administrators thereof. But Jarred Ha was found not guilty, $80,000 later, thanks to his family knowing capable lawyers.
That said, I don't believe in carrying knives as weapons for self defense. I live in Canada where carrying anything as a weapon is interpreted as being a purpose dangerous to the public peace, and considered by the "Crown" to be unlawful. A good tactical flashlight, however, does not fit the definition of weapon in the Canadian Criminal Code:
Criminal Code said:
“Weapon” means any thing used, designed to be used or intended for use
(a) in causing death or injury to any person, or
(b) for the purpose of threatening or intimidating any person
and, without restricting the generality of the foregoing, includes a firearm.
A tactical flashlight can serve to disorient and distract, especially in darker settings where an assault is more likely to occur. As well, used preemptively, it is a deterrent, as criminal violence usually occurs as an ambush by a scavenger looking for weak and unprepared prey. A tactical flashlight screams "I am aware and prepared", and if it were deployed immediately upon seeing dark silhouettes, or upon the request for the time or some change, would likely lead to far fewer instances of criminal violence, or the need to use force in self defense.
I carry knives as tools, and because they are cool. And if a predatory animal (such as might be encountered on my dark cycling commute) suddenly set upon me with intent to make a meal of me or because I unwittingly disturbed its activity, I have five inches of penetration available to me via a modded, waveable Cold Steel Voyager XL.
I would, and probably will carry a karambit (of my own making) as a box cutter.
