First, before my avatar gets into the nit-picky detail.....lemme, say, hell yes!
Sue the manufacturer. Unless and until manufacturers of this high-lethality iron are held more accountable....then we will get the same old same old. With angry socially isolated young white men shooting up WalMarts, holiday parades, music venues, elementary schools. The gun makers & peddlers do not have enough accountability and responsibility for the dangerous tools they make & sell. Give them a bigger bale-to-tote in responsibility and liability. Right now they are skating under the Protection of Lawful Commerce in Arms Act (PLCAA).
Of course, the game is in the details but right now, they are getting off nearly scot free in how they market their weaponry, and who they market it to. Lay more responsibility on 'em.
Then.....they may clean up their act.

OK, now to the nit-picking: Guys, your animosity towards Chicago has you wandering all over the landscape looking for someone to blame and lay on your burden of grievances.
Highland Park ain't Chicago.
It is a tony North Shore community, host of the world famous summerlong Ravinia music venue. Average household income = $231,000+, with 30,000 resident. 90% of whom are white.
---versus--
Chicago: Population 2.7 million. Median household income = $62,100
Lay down your heavy burden of being pissed-off at most everything.
You'll feel better.
