Baptism

So I went to my first baptism today, and of all the questions that I had, two seemed appropriate for this forum:

1) Should a deacon be concerned about what seemed to me to be obvious signs of possession? In this case, following the dousing of the baby (a different one than the one I was there to see), the baby cried uncontrollably. And this is after the exorcism took place. That's right, an exorcism, although not as hardcore as in the movie, but apparently the devil was trying for these babies prior to the service. Anyway, the deacon didn't seem concerned at all that this baby was reacting so badly to the holy water.

2) What measures are put in place to keep the holy water sanitary? When watching the end of the mass, I saw no less than 30-40 people dip fingers in this pool of water. Some of these people were children, and who knows where there hands have been. Then, for the three baptisms that took place, all the water to sprinkle on the kids came out of this pool, and the water that washed off of their heads went right back in. I saw no evidence of any hand-wash or other cleaning solution. And as still water, it seemed ripe for some sort of bacterial infestation. The father of the baptised baby, himself a university trained biologist, hypothesized that the "holy" water was antibacterial, antiviral, and antibiotic, based simply on the blessing. In my mind, we need to send some priests to Burma to bless the heck out of the water there, because they are badly in need of some clean water.
