4. 当盗窃案破案率只有18%，多数作案人不相信自己会被抓住的时候，盗窃就成为一种无风险的职业。

If the "human-testimony-centered" pattern is still taken as the dominant investigation mode, the cost of the investigation will multiply, the detection rate will decrease.
If we can use these relations in the murder case, our detection efficiency will enhance greatly, the detection rate will also rise, the crime deterrent dynamics will also enlarge.
