Yes, they can deny bail. They assess several factors; among them are your ties to the community, your past record, whether or not you a flight risk, and the seriousness of the offense you are charged with.
Judges determine bail, not the police
A couple of reasons judges refuse bail are:
Bail may be denied when the defendant appears to be a high risk for flight or represents a significant threat to the community.
if the judge thinks that the defendant is at flight risk
If the authority (Magistrate, Judge etc) believes further offences may be committed whilst on bail, the offender may abscond or the offender may interfere with witnesses before the trial.

A judge decides first of all whether the accused can be released on bail, and secondly, what the amount of the bail should be. If the judge thinks that there is too much risk that the accused will seek to flee, or may commit additional crimes while out on bail, then the judge can deny bail.
One case that supports the decision by Congress to deny bail to offenders thought to be dangerous to the community is United States v. Salerno (1987). In this case, the Supreme Court held that a federal law authorizing pretrial detention without bail for defendants charged with certain serious offenses did not violate the Eighth Amendment's prohibition on excessive bail. The Court reasoned that preventing danger to the community was a compelling government interest that justified the denial of bail in such cases.

Bail is not guaranteed in Missouri when a judge determines that the individual poses a flight risk, a danger to the community, or if there is concern about the individual obstructing justice. In such cases, the judge may deny bail or set conditions for release, such as electronic monitoring or mandatory check-ins with authorities.
It's true that not all defendants are eligible for a bail bond. In certain counties the bail schedule deems such cases as MURDER - with special circumstance as in-eligible / NOT BAILABLE. In most cases if the court also believes a defendant is a fight risk or a risk to the community it can elect to deny bail. This type of practice is common in most courts and often used when a defendant shows a consistent disregard for the court schedule.
If you are a UK citizen, you would need a passport to enter the US. If ICE runs a background check on you they MAY deny you entrance depending on the crime you are charged with. Moreover, whoever stood your bail in the UK might be a little nervous about your leaving the country, don't you think?
