The Process of Becoming Suspicious of Ulterior Motives

Discretion and Ulterior Motives in Traffic Stops: The Detection of Other Crimes and the Revenue from Tickets∗

In the United States, police officers often decide to give drivers they stop for traffic violations a warning, which imposes no fine, instead of a ticket. Officers are also legally permitted to stop drivers for the purpose of detecting other crimes. This paper addresses two questions about the role of discretion and ulterior motives in traffic stops. First, under what conditions may it be effic...

Understanding ulterior mens rea: future conduct intention is conditional intention

Where criminal offences such as attempt and conspiracy require a defendant (D) to intend future conduct, D’s intention will always be conditional. D’s intention may be explicit ly conditional (eg, D intends to rob the shop, but only if unable to pay her rent), or implic it ly conditional (eg, D intends to rob the shop, but if asked, would not do so if she found it surrounded by police). Rather ...

Biextensions of 1-motives by 1-motives

Let S be a scheme. In this paper, we define the notion of biextensions of 1-motives by 1-motives. Moreover, if M(S) denotes the Tannakian category generated by 1-motives over S (in a geometrical sense), we define geometrically the morphisms of M(S) from the tensor product of two 1-motives M1⊗M2 to another 1-motive M3, to be the isomorphism classes of biextensions of (M1, M2) by M3: HomM(S)(M1 ⊗...

Birational motives, I: pure birational motives

In the preprint [19], we toyed with birational ideas in three areas of algebraic geometry: plain varieties, pure motives in the sense of Grothendieck, and triangulated motives in the sense of Voevodsky. These three themes are finally treated separately in revised versions. The first one was the object of [21]; the second one is the object of the present paper; we hope to complete the third one ...
