"The other points involve questions of law of great importance.
First, with respect to handcuffing, the law undoubtedly is, that
police officers are not only justified, but they are bound to take
all reasonably requisite measures for preventing the escape of
those persons they have in custody for the purpose of taking them
before the magistrates; but what those reasonable measures are
must depend entirely upon circumstances, upon the temper and
conduct of the person in custody, on the nature of the charge, and
a variety of other circumstances which must present themselves to
the mind of any one. As to supposing that there is any general
rule that every one conveyed from the police station to the
magistrates' court is to be handcuffed, seems to me to be an
unjustifiable view of the law, and one on which the police
officers are mistaken. In many instances a man may be conveyed
before the magistrates without handcuffing him, and taking him
thus publicly through the streets. On the other hand, it is
necessary to take proper precautions in conveying a person in
custody to be dealt with by the magistrates; and you must say
whether, looking at all the circumstances of the case, the
defendant used unreasonable precautions in this case, or used
unnecessary measures to secure the safe custody of the plaintiff."
