What are they going to Use the Aerostat in APGEA for, again?

Is this a Tool for UNREASONABLE Search & Seizure Purposes? If you are NOT Eric Frein, any evidence this device collects about crimes other than his, should a priori be excluded from Court cases.
from CBS News:

CANADENSIS, Pa. -- Pennsylvania State Police say they're using a device similar to a weather balloon in their search for a suspect in the killing of a state trooper last month.

Trooper Tom Kelly, a state police spokesman, said Monday the Ohio Department of Transportation donated the use of the large, unmanned Mylar balloon.

He says the device provides troopers with a similar level of technology and coverage at a fraction of the cost of traditional aircraft. It's also silent.

Kelly says the balloon is experimental and among several technologies they're using in the search for 31-year-old Eric Frein.

Frein is charged with opening fire outside the Blooming Grove state police barracks on Sept. 12, killing Trooper Bryon Dickson and seriously wounding Trooper Alex Douglass.

Monday is day 45 of the search.

The manhunt is affecting Halloween in the area. CBS affiliate WYOU-TV reports that trick-or-treat night in Barrett Township was canceled. Instead, a "trunk-or-treat" event was held Sunday at a local school's parking lot, where costumed children went from car to car looking for candy.

Pennsylvania state police say they have a new silent ally in their search for suspected cop-killer Eric Frein -- an unmanned balloon equipped with high-resolution cameras. The Ohio State Department of Transportation has loaned the “eye in the sky” to act as a quieter, low-cost alternative to helicopters and other methods of aerial surveillance.

Hundreds of state troopers have taken part in the manhunt for Frein, 31, who they suspect is hiding somewhere in the woods of northeastern Pennsylvania. The “survivalist” allegedly ambushed state police barracks on Sept. 12, killing Trooper Bryon Dickson and wounding Trooper Alex Douglass. The 45-day manhunt costs roughly $500,000 every week it persists.

The balloon had been scanning Ohio prisons for potential fugitives, and will be tethered nearly 500 feet above the Pocono Mountains, where Frein is thought to be hiding following a number of unconfirmed sightings. It is 15 feet in diameter and made of Mylar, and costs only $1,000 to deploy, according to Fox News, compared to noisy police helicopters, which cost nearly $2,500 an hour.

The balloon’s cameras can spot people over 3 miles away. Police officials say they believe Frein is pinned down in an area stretching more than 5 miles.
