a little info about offshore banks and tax havens?

Is the interest I earn on money I put in an offshore bank account taxable?

Also any and all info about offshore bank accounts will be most helpful.

All interest earned by US citizens is subject to US Income Tax.

Offshore banks do not send information to the IRS; therefore, some people use those banks to evade the income tax. I don’t know what percentage get caught, but it is a felony to evade the income tax.

There's also Puerto Rico (or your local state) munis if all you want to do is dodge tax.
I used to do that heavily before I got sucked into the AMT debacle.
