If I travel to Asia and set off the more powerful fireworks available to the public there, will I be arrested by the BATF when I come back?
They conspired on US territory to commit a crime and took an actual step toward completing the crime (boarding a vessel bound for their sex tourist destination). That is enough under federal law to establish a criminal conspiracy over which the US has jurisdiction. It is not a crime to explode fireworks, so you won't be arrested by BATF if you "conspire" to do so abroad and take an actual step toward the completion of such. My fee for this smart legal opinion: $100. When can I expect payment?
there is a fairly recent federal law making "sex-tourism" involving children illegal, no matter where the perv hies off to to do it, period.
You think setting off fireworks that are illegal here and raping little boys are morally equivalent?
That's a pretty sick comparison.
