All perfect praise be to Allaah, The Lord of the Worlds. I testify that there is none worthy of worship except Allaah, and that Muhammad is His slave and Messenger.
If the person whom you mentioned in the question is killed while defending himself or his money, then we hope that he will be among the martyrs. We have already issued Fatwa 85727 about the ruling on working as a policeman, so please refer to it.
As regards the ruling on photographic pictures, then please refer to Fataawa 83249 and 83020.
With regard to your third question, it is not permissible for a Muslim to work in such a warehouse as long as there is alcohol in it, because this is helping and confirming the sin; Allaah Says (what means) {Help you one another in virtue, righteousness and piety but do not help one another in sin and transgression. And fear Allaah. Verily, Allaah is Severe in punishment.}[Quran 5:2]
Moreover, the Prophet said: "Allaah has cursed wine, its presser, the one who demands it to be pressed, its drinker, its carrier, the one to whom it is conveyed, its server, its seller, its buyer, the one who consumes its price, its purchaser and the one for whom it is purchased." [At-Tirmithi and Ibn Maajah]
In fact consuming alcohol or helping others to consume it includes all these ten kinds of people who are cursed.
Allaah Knows best.
