Smince,
If I, a rookie to this forum (not to LE or tactics), can add my 2 cents. Even though I think your search ,in this case was wrong, being prepared to do one is not. What's more important is to know under what circumstances you will enter a building/house/structure/whatever... next time!
Some in here have said the response time for LE would have been too long to wait. Why? If noone's life is in immediate danger (which in this case, it didnt sound like anyone you cared about was..) why go in? Property is not worth dying over.
If the next scenario involves a situation where you not acting may mean the death of someone, and you cant wait the 30 or so minutes it takes for LE, then perhaps go ahead and make the entry...But remember... If you dont have the tools or the training, (or aren't as good as we think) maybe leaving it to the professionals, no matter the response time, is a better idea. No sense being another statistic.
