...for 60-90 seconds, what seem to be two different small caliber arms shooting. And shooting. Suburban Brady-Bunch land Portland -between MT. Scott and Happy Valley. Slow succession of 15-18 total rounds in handgun semi-auto bursts of 2-3. Ending with a "tripple" quick succession what sounds like 9mm, .40 cal or something similar from a range of maybee 200 yards (1 block up the hill). No immediate threat to you as far as you can tell. *** ...2-3 reports from 12g shotgun or possibly 20g. Could be fireworks but if they are they are the big mortand kind, and with strage timing. It's say, October. No immediate threat to you as far as you can tell. WHAT WOULD YOU DO?? HOME ALONE NO KIDS IN THE HOUSE.
