I think there is a general misunderstanding of what Interpol does. First, Interpol focuses on criminal investigations (key) not making apprehensions (they don’t have the powers of arrest and as a fact one of their core laws prohibits them from it). Their focus is conducting investigations targeting criminal organizations, trafficking humans, drugs, financial crimes and training/support of law enforcement officers.
Next, in conducting these type of investigations, many organizations will hide from local prosecution by having their physical presence in one country while conducting their crime(s) in another country. This means the local jurisdiction is limited at best (actually stopped cold in most situations) from being able to investigate the crime. Interpol sidesteps this by have 180+ countries in it’s charter so it can complete an investigation where the victim is say, in the US but the perpetrator is in Poland. I use that example because my last major victim of identity theft (domestic victim) had been victimized by a Polish citizen. Interpol can take a case from here and work it to the other end. Without this change in law, Interpol’s investigations leading to money laundering started in the US stopped at our shores. Now they can continue an investigation which will allow local or federal officers make an arrest.
But hey, if you think some International Po-po is going to invade your residence and take you into custody for a crime you didn't commit, then maybe you should unplug your computer, throw away your cell phone and live in the woods of Idaho...just watch out for Big Foot!
Clear as mud, eh.
