Those 'checks' of identity and residence is what registration is about.
Ahh, no, its not. As I said, they were perfectly able to check the eligibility of voters before they began demanding pre-registration. Pre-registration wasn't done in America for about the first 100 years. And, if you believe it is being used to stop voter fraud now, well, I have a bridge to sell you. If anything, it provides false security allowing for far more voter fraud.
I don't know what 'tax collection' your talking about.
The 'courts'. They are all about business, collecting taxes. Certainly, there is no Justice to be found in them, aside from your occasional jury nullification.
