Because that is not what they did. Rather than having arguments about what kind of flag sticker is allowed or what constitutes a flag sticker they just said 'no stickers'. They did this because had they said you can only put up a US flag sticker someone would have sued because they were not permitted to put up a sticker of they native country or a country of their ancestors. The PA fire department decided to just nip it in the bud and said no stickers what so ever. te fact that the fire fighter cannot follow instructions or violated the rule knowingly to get attention is not my problem. If the fire dept wants to change their policy then do it. I suspect that their lawyers will advise against it.
