After watching the video, I have a few questions:
1) How did those 2 arsonists get the ladder there. They drove in a small black sedan and right there was a huge ladder. Either it was planned out a couple days before where they come and placed the ladder there. If thats the case, they can check the video cameras from previous days for more clues of how the ladder got there. Maybe it was planned out from with in and the ladder was left there on purpose just to get the insurance money?
2) Why wasn’t the sprinklers or alarms connected with the fire department. Most stores of that size have it directly connected with the fire department. If that’s the case, they would’ve been at the scene sooner and found the information quicker. As it is, all this was only revealed Motzei chag, about 24-30 hours later which is plenty of time for those 2 people to escape the country.
