somehow the cops just know from grainy 140p footage
was miraculously not shattered into pieces, which happens to all other 3d printed guns.
the very well-built gun has a particular reload quirk that was seen in the surveillance footage
the doubt about not disposing the gun is a fair point. i suppose he either wanted to seed doubt to the prosecution (as someone else claimed below), or just forgot to plan this part
would naturally spend a long period of time sitting in a public place
fair point, but i think he simply settled into routine. this is corroborated by him being "visibly shaken" and not−well-prepared to someone asking him about the murder
including the additional time it would take for the cops to respond and then arrive
he obviously did not know someone tipped him off
a random McDonald s worker
slight correction: a fellow customer told the worker. if the concern here is that he would hide his face to the worker, well he may have dropped his guard after going back to his seat
what else are you gonna scrawl hastily? luigi was just a regular upperclassman but with actual gall. opportunity doesn't wait for you to compose a manifesto
That would make sense. I'd like some links.
