Last Thursday's installment of One Panel was only being facetious about the level of violence in the proto-DC Comics of 1936, but here's a better example. Because you can always count on early Siegel & Shuster to deliver the hard-man punches and... the callous cop slayings, apparently.
A grim and off-putting example of how violence in comics has been with us since the beginning. We perhaps remember the "early days" as tame Code-approved family fare, but that was a couple of decades out at this point. To think, these guys would soon be responsible for the "wholesome" superhero archetype Superman later came to represent.
