Dear Mr. Knudsen,
I know you are monitoring this forum so this message is directed at you.
I saw a Twitter message that you sent showing some rifle shooters pointing rifles upwards.
I can only surmise that you think that this is a dangerous action and should be prohibited.
You should educate yourself before spouting fear-mongering messages. In fact you should apologize to the gentlemen that you photographed.
Herewith is a link to see a clip of the 2011 ISSF Rifle finals in Sydney, Australia. (There are many other videos like this)
This is like a warm up competition for the Olympics. These are some of the finest rifle shooters in the world, bar none.
If you do not want to watch the entire video clip, there are some screenshots from that match attached showing the normal acceptable method
of preparing to fire a shot. ..
Please observe that the finest rifle shooters in the world DO point their rifles upwards too.
Yours Truly,
The "Oldfart"
