Technology risk without safeguards

I started this effort for safeguards in July 2007. Until 2018, I did
exactly what you mention. The FCC's Office of Engineeting and Technology in
2015 has been the only government agency that replied to my email query on
jurisdiction stating the FCC does not regulate/enforce negative
improvisation of outdoor high power wireless transmitters. By 2018, I had
collected sufficient supporting data that was burdensome to send via email
and absent response of multiple governments to address this significant gap
in rule of law prompted me to put up the website competitionunlimited on

If some institution innumerable to count had agreed to investigate, I would
be very content writing code for commercial data communication systems
which is what took me to the U.S. in 1994. During my overseas deployments
with the U.S. Army National Guard, my reports to higher regarding
vulnerabilities was consistently met with unambiguous
response/acknowledgement indicating my concern is being investigated. Since
I have not had that benefit from civilian organizations, I finally reasoned
that common awareness reduces the element of surprise from an incognito

Please note that I have wrestled with "Maybe someone is just looking for
"inspiration"" for almost 13 years before bringing this to your collective
notice today.
