RoboCop/Fridge

Fridge Logic:

 * The disastrous ED-209 demonstration in the first film where the malfunctioning robot shoots a board member. It's only later when it occurs to you, "Hey, who was the moron who loaded that demonstration robot with live ammunition?"
 * Fridge Brilliance: Which slimy corporate suit has reason to sabotage the project? That's right, the one that shortly afterwards has a good cop butchered so he has a test subject for his project.
 * Frigde Brilliance: Dick Jones is so morally lacking and confident he might as well have ordered it himself. Seeing the reaction from all the co-workers in the bathroom would explain why nobody would talk back.
 * Loading multi-ton mecha-Cain up with a arsenal, taking him to a press conference and then waving a drug canister under his nose. What Could Possibly Go Wrong? Wait, Robo's turned up, lets wave his gun-safety controls under his nose.
 * The Old Man doesn't know that Cain is a Nuke addict; it's unlikely he even knows who Doctor Fax even used to make Robocop 2, and even if she couldn't keep that information from him, she wouldn't have told him that their hold (or more precisely, her perceived hold) was based on feeding his habit. She's too self-confident in her own good; while she's waving the remote around she's shouting at everyone "He's harmless, he's not even armed!" She clearly didn't make the logical leap that if he was already misbehaving, he would probably go a lot farther.
 * Also, in what can only be a case of learning from previous mistakes, they at least didn't load the weapons systems.
 * The first movie started off bad, then it got worse to Robocop, a Law officer named Murphy. Think about it.
 * Fridge Brilliance: The reason why ED-209 shot Kinney even after he put the gun down: the robot says "put down your weapon," and Kinney throws it away. ED-209's sensors did not register Kinney's motion as actually setting the gun down as instructed, so, to ED-209, Kinney hadn't complied and still had the gun.
 * If that was the case, then shouldn't Jones expected that rather then saying it was a glitch?
 * Not unless it hadn't come up before.
