We take safety steps that reduce the risks of everything from chain saws (so they don't kick back and cut off an arm) to refrigerators (so kids can't lock themselves inside). But firearms have been exempt. Companies make cellphones that survive if dropped"
...but none of these items are protected by an Amendment in the Bill of Rights.

Attention sports fans:
The sensor/indicator of a loaded gun is a RED HERRING for law suits and lawyer seeking a new cash cow.
No matter how good it may be some fool will claim the "indicator showed unloaded" or "too hard to read".
Proper gun safety lesson number one is ALWAYS ALWAYS ALWAYS treat, assume and handle ALL guns as if loaded. Somebody hands you a gun they just checked to be empty YOU check it again. No indicator will work for a round in the chamber of an automatic without compromising safety from the explosion.
