Perhaps the focus should be less on the LEGALITY of consuming alcohol, even on private property, but rather on the physiological effects that alcohol produces in the human body. Does ANYONE want to be at all impaired if they need to use their gun?
There is ample evidence dating back to the 1950s that alcohol impairs function, even in small doses, (example, https://www.utsa.edu/utsapd/Crime_Preve ... Skills.pdf
Anyone who disbelieves can do their own google search.
While the evidence that I am posting relates to driving, the generalizations are obvious:
JUDGMENT: The ability to make sound and responsible decisions.
• Alcohol affects your mental functions first, and
judgment is the first to go, which means reason
and caution are quickly reduced. •Can be affected as low as .02% BAC.
CONCENTRATION: The ability to shift attention from one point of action to another.
• Alcohol impairs a driver's ability to concentrate
on the multiple tasks involved in driving, such
as vehicle speed, position of the vehicle, other traffic on the road,
tuning the radio, and
participating in conversation with passengers.
•Leaves the driver concentrating on a singular action.
COMPREHENSION: The ability to understand situations,
signs, and signals.
• Alcohol impairs the driver's ability to "interpret"
situations, signs, and/or signals which a driver
must understand and/or respond to quickly to be safe on the road.
• Leaves the driver easily confused and not able
to respond to emergency situations or to
comprehend the meaning of simple signals
(ie: running through a stop sign). COORDINATION: The ability to coordinate motor skills.
• Impairs ability to coordinate motor skills, beginning with the
fine motor skills (putting key in
ignition) up to gross motor skills (walking to the car).
• Loss of coordination severely affects
reaction time and ability to react.
VISION & HEARING ACUITY: The ability to see and hear
• Reduces visual acuity up to 32%.
• Reduces peripheral vision resulting in tunnel vision.
• Impairs ability to judge distance and depth perception (position of car).
• Dilates pupil, slows down reactions of pupil
resulting in problems with on-coming headlights
(glare) and "blind" driving.
• Reduces the ear's ability to hear, muffling sounds,
and interfering with the ability to determine
the direction of sounds. REACTION TIME: Ability to see and understand a situation, then take an action.
• Severely reduced due to impairment of comprehension and coordination in particular.
•Slows down reaction time by 15-25%,
resulting in crashes and accidents which could have been
avoided if no alcohol was in the system.
