本文主要探究一个具有争议的刑事案例的定性问题。该案例大意为:被告人于某,胁迫赶走公路收费人员并假扮其身份收取过路费。由于对于被告的行为严重破坏社会秩序,已属于刑事犯罪,但对于行为人行为的性质却难以得到定论。作者希望通过对案件当事人所做的违法行为的性质、罪数形态来多种角度论述,对该案件希望做较深入探究,以帮助弥补司法不足。 This article explores the qualitative issues of a controversial criminal case. The case was to the effect that the defendant, Yu Moumou, coerced the evacuation of toll collectors and assumed their identity. Since it is already a criminal offense to seriously dehumanize the social order against the defendant, the nature of the perpetrator’s behavior can hardly be definitive. The author hopes to elaborate on the nature of the illegal acts done by the parties involved in the case and the types of guilty plea, and hopes that the case can be further explored to help make up for the lack of justice.
