4 accidental deaths within a 2 year period?  I'm supremely sorry these events occurred, but compared to other reason for accidental deaths this is a drop in the bucket.  Why focus on the fact that guns were involved?  In comparison lets look at the number of auto accidents that resulted in death during that same period.  That number is 1035 according to CDOT data: https://www.codot.gov/library/traffic/safety-crash-data/fatal-crash-data-city-county.  Sure, this data isn't broken down into the fear mongering tactic of counting involved children, but you get the picture of the scale that we're talking about.  Accidental gun related deaths are a very small problem compared to other accidental sources.

No one ever suggests that cars should be illegal based on the number of deaths they cause, and owning or driving a car isn't even a constitutional right.  You may not choose to exercise your 2nd amendment right, but many people do.  Taking it away from them would be the wrong thing to do.
