	except (requests.exceptions.RequestException, ValueError) as req_err:
	logger.warning("Failed getting forensics for incidentID {} from profileID {}. Error: {}. Continuing.".format(incident["_id"], incident["profileID"], req_err))
	continue

This continues which leads to another pop(0), erasing the incident with the error.
