In the A game, the crank is located in the evidence room ontop the cabinet...make your way through the room and its the last one against the wall... In the B game, Leon finds it in the Chest in the back of the Chief's Armor Room(where you find and talk to Sherry as Claire in CLaire A) and Claire finds it in the Dog Kennel in the Basement Prison...
the details definitely were not overlooked as far as item placement goes...everything is right where you'd expect it to be in the B quest from the A quest. CAPCOM can be amazing when they put a little effort.
maybe it's just me, but the items being located in different spots from the different quests kind of gives the game a haunted house vibe, if you're like me and think about ghosts (or zombies, it doesn't matter) moving the items around. I like thinking about that.
They could've been REAL SADISTIC sonsof*****es and messed around with two cranks, ala RE1/3. --- All rights reserved, all wrongs righted, all lefts ridiculed, two wrongs don't make a right, but three rights make a left.
