He apparently has a vast knowledge of terrorist/insurgent TTPs. Not only that, but he can identify how their strengths match up with "our" gaps; especially when it comes to the LAPD. He made mention of the body armor used by the LAPD...and demolitions classes. It is pretty likely he knows how to make bombs more stable than AQIZ, AQIM etc with off the shelf supplies here......and use them against the TTPs of LAPD.
He almost seems envious of the jihadis and what he perceives to be their invincibility (their name lives on) and "higher purpose." Only, he has centered his own morality and "DNA" as the higher purpose.......that he is trying to promote. HE WANTS THEM [LAPD] TO FIND HIM. HE NEEDS TO BE A MARTYR.
He is trying to use agitprop, and a murder and intimidation campaign (terrorist favorite) to goad the LAPD into acting. Any move they try to make against him will be flipped back as excessive use of force.....to "prove" his point; and hopefully garner more sympathy/support - it will be a demonstration of sorts that the LAPD infringes upon civil rights (increased traffic stops, checkpoints, dragnets, etc).
They need to find this guy on the quiet - he told them how, and they need to off him. This is the #sshole they need SWAT for, not Amish selling non-pasteurized milk.
If this lasts for long it could light the fuse in LA. Lots of crazy grievance gangsters just waiting for an excuse.
