Why do people keep bringing up the treatment of Manning in a military prison re: Snowden?

44. RCM 304 and 305

Pretrial confinement only requires probable cause, and is at the command's discretion

http://www.loc.gov/rr/frd/Military_Law/pdf/MCM-2012.pdf‎

The pertinent paragraphs:

(d) When a person may be confined. No person may
be ordered into pretrial confinement except for prob-
able cause. Probable cause to order pretrial confine­
ment exists when there is a reasonable belief that:
(1) An offense triable by court-martial has been
committed;
(2) The person confined committed it; and
(3) Confinement is required by the circumstances.

...

(2) Action by commander.
(A) Decision. Not later than 72 hours after the
commander’s ordering of a prisoner into pretrial
confinement or, after receipt of a report that a mem­
ber of the commander’s unit or organization has
been confined, whichever situation is applicable, the
commander shall decide whether pretrial confine-
ment will continue. A commander’s compliance
with this subsection may also satisfy the 48-hour
probable cause determination of subsection R.C.M.
305(i)(1) below, provided the commander is a neu­
tral and detached officer and acts within 48 hours of
the imposition of confinement under military con­
trol. Nothing in subsections R.C.M. 305(d), R.C.M.
305(i)(1), or this subsection prevents a neutral and
detached commander from completing the 48-hour
probable cause determination and the 72-hour com­
mander’s decision immediately after an accused is
ordered into pretrial confinement.
(B) Requirements for confinement. The com­
mander shall direct the prisoner’s release from pre-
trial confinement unless the commander believes
upon probable cause, that is, upon reasonable
grounds, that:
(i) An offense triable by a court-martial has
been committed;
(ii) The prisoner committed it; and
(iii) Confinement is necessary because it is
foreseeable that:
(a) The prisoner will not appear at trial,
pretrial hearing, or investigation, or
(b) The prisoner will engage in serious
criminal misconduct; and
(iv) Less severe forms of restraint are inade­-
quate.
Serious criminal misconduct includes intimidation
of witnesses or other obstruction of justice, serious
injury of others, or other offenses which pose a
serious threat to the safety of the community or to
the effectiveness, morale, discipline, readiness, or
safety of the command, or to the national security of
the United States. As used in this rule, “national
security” means the national defense and foreign
relations of the United States and specifically in­
cludes: a military or defense advantage over any
foreign nation or group of nations; a favorable for­-
eign relations position; or a defense posture capable
of successfully resisting hostile or destructive action
from within or without, overt or covert.
