IP address leads to arrest??

[nihil]

IP = ID?? How can this be possible?

The NSA and the Homeland Security Act make it so. Maybe the perp didn't fancy a holiday in Cuba?............... maybe they just beat a fess out of him with a length of pressure hose?

A man in WNY was arrested and sentenced to a year in jail over an email with the sole piece of evidence being an IP address?

Errr, excuse me, in a civilised country you would be arrested, charged, arraigned, tried, judged, then sentenced or aquitted

Also, to obtain a conviction in a civilised society, you need to satisfy the Court as to:

1. Opportunity
2. Ability
3. Motive

(- and a wireless IP address at that?! -)

There is no such thing. An IP address is an IP address.......... period.

How can they determine from an IP address who in the house or on a network is actually on the computer?

If it is your house and your network, why should they care? you are guilty until proven innocent. It is the same as if your handgun is used in a crime, or your automobile.

The onus of proof is on you..........
