Rather than the Las Vegas attack, I’d rather expect DEFCON to be hurt by the arrest of Marcus Hutchins. Surely it should have given cold feet to some of the most interesting guests and speakers.
I have not seen remarks in the security community that people were afraid of being arrested out of the blue like Marcus Hutchins.
This stuff happens every year, probably multiple times.
The people worried about the FBI already avoid the US.
Had I been older, they’d probably have arrested me.
I ended up being arrested months later by local police.
