Sorry, Reaver, but that's just not true. While they would have to fill out some paperwork on you since you have a SIN, that EVO SIN only provides you limited protections off EVO corporate property. Think about it this way: how much does a US Citizen's citizenship protect them in Mexico, Japan, or Somalia?
In Mexico or Japan?
A fair bit. Somalia... does it even have a stable government?
While you are still bound by the rules of the zone you are in, the simple fact that you are citizen of a foreign country (in this case a Corp), means you get a "few" extra privledges that a regular citizen does not. But that is also determined by the nature of treaties between the respective governments. Case in point, Italy and USA. USA and Canada, Canada and France, USA and France..... each country has a different level of co-operation with different governments....
But the simple fact that you are a Citizen means they HAVE to follow procedures and paper work when dealing with you, and not the "50 grain" solution...
which, in the world of SR, is one HUGE advantage that the SINner has over the other members of their crew.... and yet one more reason for their distrust.
