They are very old cases and I don't recall the coverage except for one of them.
The one I recall, certainly was covered in the media. (note I only read through the first half of this stuff) So what's your point? Are you claiming none of these were covered by the media? Or are we doing a TB shift where instead of supporting your crazy thesis that acts of gun heroism are not covered by the media, we are now offering evidence that acts of gun heroism do in fact exist? I never made, nor would I support the assertion that gun heroism does not exist, so such evidence should be addressed to somebody who cares.
-edit- My last (run-on) sentence did not make any sense the first time I framed it.
