Double Glazed Windows at Boston Firecracker DEBUNKED

Many comments stating that the left sided window of the Lenscrafter building was double glazed due to seeing a reflection of the cops. Simple physics show that this can't be so. Image is faked to give this illusion to make out the windows weren't smashed from the inside. Very unlikely that one window is single and other double glazed side by side. Without a doubt the right sided window is completely smashed.
