Article update: Las Vegas Shooting 1-Oct-2017 – An acoustic analysis and personal impressions

I knew about the supersonic boom produced by a projectile traveling faster than the speed of sound when i originally did my acoustic analysis of the Vegas shooting, however i ignored this for what ever reason and instead attributed the first sounds to reach the concert venue as bullet impacts. I think i was thrown off by the fact that in some cases these early sounds, followed 30-40 ms. later by the muzzle blast, were indeed bullets impacting objects including metal and glass as can clearly be heard in at least one of the videos.

Whatever the case, i have corrected the article to include information about the supersonic shock waves produced by projectiles which, by the way, is why silencers are not effective on high velocity rifles. In the end this oversight should make absolutely no difference in my calculations because the sonic blast of a projectile is produced by the projectile, not the gun, and so it would have been heard at almost exactly the same time as that same projectile impacted an object.

Anyway, this was a rather stupid oversight on my part and i will certainly own up to it.

2019 Christchurch Mosque Shooting study resources

I decided to post links to both the helmet cam video and manifesto as apparently supplied by Brenton Tarrant regarding his alleged murderous rampage upon the Muslim community at the Al Noor Mosque and Linwood Islamic Centre in Christchurch, New Zealand, on March 15, 2019. From Wikipedia:

The Christchurch mosque shootings were two consecutive terrorist mass shootings at the Al Noor Mosque and the Linwood Islamic Centre in Christchurch, New Zealand, during Friday Prayer on 15 March 2019. The attacks began at the Al Noor Mosque in the suburb of Riccarton at 1:40 pm, and continued at the Linwood Islamic Centre at about 1:55 pm.

The attacks killed 50 people and injured 50 more. A 28-year-old Australian man and white supremacist described in media reports as part of the "alt-right", was arrested and charged with murder. The attacks have been linked to an increase in white supremacism and alt-right extremism globally observed since the mid-2010s. The suspect published a manifesto and live-streamed the first attack on Facebook Live. It is the deadliest mass shooting in modern New Zealand history.

I am posting links to the video and manifesto because i am very much against censorship and New Zealand, as well as all of the mainstream social media platforms, are aggressively censoring this material thereby infringing upon the inherent human right of free speech. I think censoring these materials, or any materials, is an incredibly Orwellian and utterly despicable action for governments and corporations to take, especially in the case of New Zealand who is threatening 10 year prison terms for anyone distributing the video. While one could pose the dubious argument that making such materials easily available could possibly foster further terrorist acts, one could also easily and logically counter this. I would also argue that it is important for people to see this material. In the case of the video, it is a unique visual record of what a warped, socially compartmentalized human being is capable of and it is far more powerful than words. It is also evidence that must be available to independent researchers because, as most of us know, government officials often get it wrong, either by accident or, more likely, on purpose (9/11, JFK, RFK, MLK, etc.). Lastly, i wonder if people would continue to allow the illegal and immoral geopolitical wars in the Middle East and the genocide in Palestine if images of all the women and children slaughtered in these beastly actions were displayed in the mainstream news for all to see as was the case in Vietnam on occasion? Governments (the tools of corporations, finance and the so-called 'elite') know how powerful such images are and this is one reason why their mouthpieces (the mainstream media companies) will not allow them to be published.

Any New Zealanders wishing to obtain copies of this material should probably take the precaution of using a VPN or Tor.
