Dumb.
Via Tech Insider:
Apple is replacing the pistol emoji with a squirt gun emoji, the company announced on Monday.
New emoji icons, including emoji that depict female athletes and professionals, will be included as part of a new beta version of iOS for iPhones and iPads.
But as part of the latest update, Apple actually removed an emoji. Apple has replaced the handgun emoji with a bright green icon that looks like a classic Super Soaker water pistol.
This appears to be an Apple decision to change its icon — not a decision by Unicode, the body that writes the standards for computer characters, including emoji.
