This does point out the one weakness of the 10 YO daughter rule.. People have different beliefs as to what is acceptable for their children to see.
I seem to remember a link to a video on youtube being posted here of a similar subject firing a full auto with replies commenting on the brass catcher without any outcry from the 'community'. But you had to click through to actually see it...
I personally have no objection to my actual 10 year old daughter (as of Dec 2nd) seeing this photo but would understand if others did.
Reasonable gun control is hitting your target with the first shot.
With all due respect to the poster who said "you always have the ability to NOT LOOK. ", you are correct. But It is much easier to make a decision if there is more information on which to base that decision.
The title of the post gave no warning or information as to the content of the post ( no offense intended to the original poster).
The "10 year old daughter rule" has been in effect and seemingly successful for a good while. There are other forums that don't have such rules and we all have the ability to partake of those options.
