With DC, current flows one way through the conductor from (-) to (+) that is all, with AC current flows both ways, back and forth FAST, the speed at which it moves back and forth is measured called its frequency measured in Herz, in your home electricity moves back and forth through the circuit's 60 times a second or 60 Herz, ironically this frequency has been found to be the most dangerous to our body. AC is much more brutal to our tissues, in a study of over 300 cases of electrical deaths over 3/4 of them were from AC, and on the average had 40% more burn dammage.
I bet most of those deaths were coused by high voltage AC.Why does AC kill more people annually than DC?Because DC is less commonly used in every day life.That was a nice biased fact you found.

Amperage cannot be present without voltage.

Actually AC is known as the death current, if you have any arguments with that you can ask Thomas Edison, as he is the one who said so.

Even static electricity measures a few milli amps.I have never come across that scenario with your explanation before.If there is voltage present and there is a discharge(usage there of), that discharge or consumption of electricity will be measured in amps.No matter how small, it will be measured in amps.The electrical discharge of your brain can be measured in amps.
As far as the Thomas Edison comment, yes he invented batteries.They were static derived though.This was achieved by strapping a metal rod on the end of a glass bottle and spinning a leather wheel against the tip of the metal rod creating and gathering the static electricity.The metal rod would store it inside the bottle creating a battery.He was even knocked unconciouse by a series of those batteries a couple of times......---- Im not going to explain this to you...you need to read about T.E a little more.

1/1000(milli amp) of an amp=voltage present.So your theory that you can have voltage present with no amperage is busted.

Re: wtf was this firefighter thinking?
dc is more dangerous simply by the fact that if you get some dc current flowing throught you you tend to clamp on to it and fry. That is very dangerous even at a "low" voltage. They say that of all the electrocutions and accidents that the most people are killed by 277v. If you have no current flowing through you then you will not be shocked or electrocuted. That is how birds land on live lines and dont get smoked, no path to ground or difference in potential. This is also how guys do work BAREHANDED on 765000v energized transmission lines.
