I would have guessed as much from reading your posts. I have a feeling you have never smelled concentrated aqueous HCl, or the gas it off puts. I'm not sure why, but this is how every CN thread seems to go.
why not re-read this thread as well as accounts of the gas chambers used in Germany during ww2 as well as accounts of it used in the US for executions? CN isn't a magic off switch for life, and it's usage historically has been more geared around certainty (taken orally or used as a gas in closed systems) than peacefulness. Trying to convert it to HCN gas is one of the absolute worst ways to use it.
in addition to harming others, simply because a high concentration can kill rapidly often does not work out that way in practice. Why? Because it takes time, volume, and lack of circulation to achieve this concentration. you seem to be unwilling to consider the documented cases I've mentioned more than once. I'm out of this thread.
you are free to do what you want to you, but I sure as hell hope you aren't reckless or malicious enough to harm others.
