Did he force the residents to drink the tap water?
Pretty much, yeah.
Really? when and how did Rick Snyder go about doing this? Did he force the dumb ***** in flint to use lead plumbing too?

Are you even paying attention? Do you know anything about this? Or are you just talking for the sake of hearing your own voice?
WTF are you babbling about? Or didn't you realize that lead wasn't introduced into the water supply naturally?
There is lead in most water pipes. What happened was that the water source was switched from lake water to river water. River water is more corrosive due to the higher levels of salt and must be treated before it enters the pipes or it will corrode them, releasing lead into the water.
The state KNEW that the lead levels were going up. Instead of doing something about it when they first learned of it, they tried to discredit all the people that pointed the fact out to them.
Gross and willful negligence poisoned the people of Flint.
